-
-Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline enabled application. It is fast, portable, renderer agnostic and self-contained (no external dependencies).
-
-Dear ImGui is designed to enable fast iteration and empower programmers to create content creation tools and visualization/ debug tools (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal, and thus lacks certain features normally found in more high-level libraries.
-
-Dear ImGui is particularly suited to integration in realtime 3D applications, fullscreen applications, embedded applications, games, or any applications on consoles platforms where operating system features are non-standard. 
-
-Dear ImGui is self-contained within a few files that you can easily copy and compile into your application/engine:
-
-  - imgui.cpp
-  - imgui.h
-  - imgui_demo.cpp
-  - imgui_draw.cpp
-  - imgui_internal.h
-  - imconfig.h (empty by default, user-editable)
-  - stb_rect_pack.h
-  - stb_textedit.h
-  - stb_truetype.h
-
-No specific build process is required. You can add the .cpp files to your project or #include them from an existing file.
-
-Your code passes mouse/keyboard inputs and settings to Dear ImGui (see example applications for more details). After Dear ImGui is setup, you can use it like in this example:
-
-![screenshot of sample code alongside its output with dear imgui](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/code_sample_01.png)
-
-Dear ImGui outputs vertex buffers and simple command-lists that you can render in your application. The number of draw calls and state changes is typically very small. Because it doesn't know or touch graphics state directly, you can call ImGui commands anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate dear imgui with your existing codebase. 
-
-_A common misunderstanding is to think that immediate mode gui == immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes, as the gui functions are called by the user. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._
-
-Dear ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game making editor/framework, etc.  
-
-Binaries/Demo
--------------
-
-You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let me know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here:
-- [imgui-demo-binaries-20171013.zip](http://www.miracleworld.net/imgui/binaries/imgui-demo-binaries-20171013.zip) (Windows binaries, Dear ImGui 1.52 WIP built 2017/10/13, 5 executables)
-
-Bindings
---------
-
-Integrating Dear ImGui within your custom engine is a matter of wiring mouse/keyboard inputs and providing a render function that can bind a texture and render simple textured triangles. The examples/ folder is populated with applications doing just that. If you are an experienced programmer it should take you less than an hour to integrate Dear ImGui in your custom engine, but make sure to spend time reading the FAQ, the comments and other documentation!
-
-_NB: those third-party bindings may be more or less maintained, more or less close to the spirit of original API and therefore I cannot give much guarantee about them. People who create language bindings sometimes haven't used the C++ API themselves (for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, please check the original C++ version first!_

-Frequently Asked Question (FAQ)
--------------------------------
-
-<b>Where is the documentation?</b>
-
-- The documentation is at the top of imgui.cpp + effectively imgui.h. 
-- Example code is in imgui_demo.cpp and particularly the ImGui::ShowTestWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output. 
-- Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder. 
-- We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort.
-
-<b>Which version should I get?</b>
-
-I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master. The library is fairly stable and regressions tend to be fixed fast when reported. You may also want to checkout the [navigation branch](https://github.com/ocornut/imgui/tree/navigation) if you want to use Dear ImGui with a gamepad (it is also possible to map keyboard inputs to some degree). The Navigation branch is being kept up to date with Master.
-
-<b>Why the odd dual naming, "dear imgui" vs "ImGui"?</b>
-
-The library started its life and is best known as "ImGui" only due to the fact that I didn't give it a proper name when I released it. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations. It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "dear imgui" that people can use to refer to this specific library in ambiguous situations.
-
-<b>What is ImTextureID and how do I display an image?</b>
-<br><b>I integrated Dear ImGui in my engine and the text or lines are blurry..</b>
-<br><b>I integrated Dear ImGui in my engine and some elements are disappearing when I move windows around..</b>
-<br><b>How can I have multiple widgets with the same label? Can I have widget without a label? (Yes). A primer on labels/IDs.</b>
-<br><b>How can I tell when Dear ImGui wants my mouse/keyboard inputs VS when I can pass them to my application?</b>
-<br><b>How can I load a different font than the default?</b>
-<br><b>How can I easily use icons in my application?</b>
-<br><b>How can I load multiple fonts?</b>
-<br><b>How can I display and input non-latin characters such as Chinese, Japanese, Korean, Cyrillic?</b>
-<br><b>How can I preserve my Dear ImGui context across reloading a DLL? (loss of the global/static variables)</b>
-<br><b>How can I use the drawing facilities without an Dear ImGui window? (using ImDrawList API)</b>
-
-See the FAQ in imgui.cpp for answers.
-
-<b>How do you use Dear ImGui on a platform that may not have a mouse or keyboard?</b>
-
-I recommend using [Synergy](http://synergy-project.org) ([sources](https://github.com/symless/synergy)). In particular, the _src/micro/uSynergy.c_ file contains a small client that you can use on any platform to connect to your host PC. You can seamlessly use your PC input devices from a video game console or a tablet. Dear ImGui allows to increase the hit box of widgets (via the _style.TouchPadding_ setting) to accommodate a little for the lack of precision of touch inputs, but it is recommended you use a mouse to allow optimising for screen real-estate. You can also checkout the beta [navigation branch](https://github.com/ocornut/imgui/tree/navigation) which provides support for using Dear ImGui with a game controller.
-
-<b>Can you create elaborate/serious tools with Dear ImGui?</b>
-
-Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools).
-
-Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might requires you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful.
-
-<b>Is Dear ImGui fast?</b>
-
-Probably fast enough for most uses. Down to the foundation of its visual design, Dear ImGui is engineered to be fairly performant both in term of CPU and GPU usage. Running elaborate code and creating elaborate UI will of course have a cost but Dear ImGui aims to minimize it.
-
-Mileage may vary but the following screenshot can give you a rough idea of the cost of running and rendering UI code (In the case of a trivial demo application like this one, your driver/os setup are likely to be the bottleneck. Testing performance as part of a real application is recommended).
-
-![performance screenshot](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v138/performance_01.png)
-
-This is showing framerate for the full application loop on my 2011 iMac running Windows 7, OpenGL, AMD Radeon HD 6700M with an optimized executable. In contrast, librairies featuring higher-quality rendering and layouting techniques may have a higher resources footprint.
-
-If you intend to display large lists of items (say, 1000+) it can be beneficial for your code to perform clipping manually - one way is using helpers such as ImGuiListClipper - in order to avoid submitting them to Dear ImGui in the first place. Even though ImGui will discard your clipped items it still needs to calculate their size and that overhead will add up if you have thousands of items. If you can handle clipping and height positionning yourself then browsing a list with millions of items isn't a problem.
-
-<b>Can you reskin the look of Dear ImGui?</b>
-
-You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as Dear ImGui is designed and optimised to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Below is a screenshot from [LumixEngine](https://github.com/nem0/LumixEngine) with custom colors + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged):
-
-![LumixEngine](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v151/lumix-201710-rearranged.png)
-
-<b>Why using C++ (as opposed to C)?</b>
-
-Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience.
-
-There is an reasonably maintained [c-api for ImGui](https://github.com/Extrawurst/cimgui) by Stephan Dilly designed for binding in other languages. I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Links](https://github.com/ocornut/imgui/wiki/Links) for third-party bindings to other languages.

-Developed by [Omar Cornut](http://www.miracleworld.net) and every direct or indirect contributors to the GitHub. The early version of this library was developed with the support of [Media Molecule](http://www.mediamolecule.com) and first used internally on the game [Tearaway](http://tearaway.mediamolecule.com). 
-
-I first discovered imgui principles at [Q-Games](http://www.q-games.com) where Atman had dropped his own simple imgui implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating on it.

+See [Software using dear imgui](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui), [Quotes](https://github.com/ocornut/imgui/wiki/Quotes) and [Gallery](https://github.com/ocornut/imgui/issues/2265) pages to get an idea of its use cases.
+
+Dear ImGui is self-contained within a few files that you can easily copy and compile into your application/engine:
+- imgui.cpp
+- imgui.h
+- imgui_demo.cpp
+- imgui_draw.cpp
+- imgui_widgets.cpp
+- imgui_internal.h
+- imconfig.h (empty by default, user-editable)
+- imstb_rectpack.h
+- imstb_textedit.h
+- imstb_truetype.h
+
+No specific build process is required. You can add the .cpp files to your project or #include them from an existing file.
+
+### Usage
+
+Your code passes mouse/keyboard/gamepad inputs and settings to Dear ImGui (see example applications for more details). After Dear ImGui is setup, you can use it from \_anywhere\_ in your program loop:
+
+Code:
+```cpp
+ImGui::Text("Hello, world %d", 123);
+if (ImGui::Button("Save"))
+{
+    // do stuff
+}
+ImGui::InputText("string", buf, IM_ARRAYSIZE(buf));
+ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
+```
+Result:
+<br>![sample code output](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v160/code_sample_02.png)
+<br>_(settings: Dark style (left), Light style (right) / Font: Roboto-Medium, 16px / Rounding: 5)_
+
+Code:
+```cpp
+// Create a window called "My First Tool", with a menu bar.
+ImGui::Begin("My First Tool", &my_tool_active, ImGuiWindowFlags_MenuBar);
+if (ImGui::BeginMenuBar())
+{
+    if (ImGui::BeginMenu("File"))
+    {
+        if (ImGui::MenuItem("Open..", "Ctrl+O")) { /* Do stuff */ }
+        if (ImGui::MenuItem("Save", "Ctrl+S"))   { /* Do stuff */ }
+        if (ImGui::MenuItem("Close", "Ctrl+W"))  { my_tool_active = false; }
+        ImGui::EndMenu();
+    }
+    ImGui::EndMenuBar();
+}
+
+// Edit a color (stored as ~4 floats)
+ImGui::ColorEdit4("Color", my_color);
+
+// Plot some values
+const float my_values[] = { 0.2f, 0.1f, 1.0f, 0.5f, 0.9f, 2.2f };
+ImGui::PlotLines("Frame Times", my_values, IM_ARRAYSIZE(my_values));
+
+// Display contents in a scrolling region
+ImGui::TextColored(ImVec4(1,1,0,1), "Important Stuff");
+ImGui::BeginChild("Scrolling");
+for (int n = 0; n < 50; n++)
+    ImGui::Text("%04d: Some text", n);
+ImGui::EndChild();
+ImGui::End();
+```

+
+### How it works
+
+Check out the References section if you want to understand the core principles behind the IMGUI paradigm. An IMGUI tries to minimize superfluous state duplication, state synchronization and state retention from the user's point of view. It is less error prone (less code and less bugs) than traditional retained-mode interfaces, and lends itself to create dynamic user interfaces.
+
+Dear ImGui outputs vertex buffers and command lists that you can easily render in your application. The number of draw calls and state changes required to render them is fairly small. Because Dear ImGui doesn't know or touch graphics state directly, you can call its functions  anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate dear imgui with your existing codebase.
+
+_A common misunderstanding is to mistake immediate mode gui for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the gui functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._
+
+Dear ImGui allows you create elaborate tools as well as very short-lived ones. On the extreme side of short-liveness: using the Edit&Continue (hot code reload) feature of modern compilers you can add a few widgets to tweaks variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game making editor/framework, etc.
+
+Demo Binaries
+-------------
+
+You should be able to build the examples from sources (tested on Windows/Mac/Linux). If you don't, let me know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here:
+- [imgui-demo-binaries-20181008.zip](http://www.miracleworld.net/imgui/binaries/imgui-demo-binaries-20181008.zip) (Windows binaries, Dear ImGui 1.66 WIP built 2018/10/08, master branch, 5 executables)
+
+The demo applications are unfortunately not yet DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at different scale, and scale your Style with `style.ScaleAllSizes()`.
+
+Bindings
+--------
+
+Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading one texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that. If you are an experienced programmer at ease with those concepts, it should take you about an hour to integrate Dear ImGui in your custom engine. Make sure to spend time reading the FAQ, the comments and other documentation!
+
+_NB: those third-party bindings may be more or less maintained, more or less close to the original API (as people who create language bindings sometimes haven't used the C++ API themselves.. for the good reason that they aren't C++ users). Dear ImGui was designed with C++ in mind and some of the subtleties may be lost in translation with other languages. If your language supports it, I would suggest replicating the function overloading and default parameters used in the original, else the API may be harder to use. In doubt, please check the original C++ version first!_

+
+Frequently Asked Question (FAQ)
+-------------------------------
+
+**Where is the documentation?**
+
+- The documentation is at the top of imgui.cpp + effectively imgui.h.
+- Example code is in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. It covers most features of ImGui so you can read the code and call the function itself to see its output.
+- Standalone example applications using e.g. OpenGL/DirectX are provided in the examples/ folder.
+- We obviously needs better documentation! Consider contributing or becoming a [Patron](http://www.patreon.com/imgui) to promote this effort.
+- Your programming IDE is your friend, find the type or function declaration to find comments associated to it.
+
+**Which version should I get?**
+
+I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported.
+
+You may also peak at the [Multi-Viewport](https://github.com/ocornut/imgui/issues/1542) and [Docking](https://github.com/ocornut/imgui/issues/2109) features in the `docking` branch. Several projects are using this branch and it is kept in sync with master regularly.
+
+**Who uses Dear ImGui?**
+
+See the [Quotes](https://github.com/ocornut/imgui/wiki/Quotes) and [Software using dear imgui](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui) pages for an (incomplete) list of games/software which are publicly known to use dear imgui. Please add yours if you can!
+
+**Why the odd dual naming, "Dear ImGui" vs "ImGui"?**
+
+The library started its life as "ImGui" due to the fact that I didn't give it a proper name when I released 1.0 and had no particular expectation that it would taker off. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations (e.g. Unity uses it own implementation of the IMGUI paradigm). It seemed confusing and unfair to hog the name. To reduce the ambiguity without affecting existing codebases, I have decided on an alternate, longer name "Dear ImGui" that people can use to refer to this specific library in ambiguous situations. Please try to refer to it as "Dear ImGui".
+
+**How can I tell whether to dispatch mouse/keyboard to imgui or to my application?**
+<br>**How can I display an image? What is ImTextureID, how does it works?**
+<br>**How can I have multiple widgets with the same label or with an empty label? A primer on labels and the ID Stack.**
+<br>**How can I use my own math types instead of ImVec2/ImVec4?**
+<br>**How can I load a different font than the default?**
+<br>**How can I easily use icons in my application?**
+<br>**How can I load multiple fonts?**
+<br>**How can I display and input non-latin characters such as Chinese, Japanese, Korean, Cyrillic?** ([example](https://github.com/ocornut/imgui/wiki/Loading-Font-Example))
+<br>**How can I interact with standard C++ types (such as std::string and std::vector)?**
+<br>**How can I use the drawing facilities without an Dear ImGui window? (using ImDrawList API)**
+<br>**How can I use this without a mouse, without a keyboard or without a screen? (gamepad, input share, remote display)**
+<br>**I integrated Dear ImGui in my engine and the text or lines are blurry..**
+<br>**I integrated Dear ImGui in my engine and some elements are disappearing when I move windows around..**
+<br>**How can I help?**
+
+See the FAQ in imgui.cpp for answers.
+
+**Can you create elaborate/serious tools with Dear ImGui?**
+
+Yes. People have written game editors, data browsers, debuggers, profilers and all sort of non-trivial tools with the library. In my experience the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library.
+
+Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might requires you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient and powerful.
+
+**Can you reskin the look of Dear ImGui?**
+
+You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, fonts. However, as Dear ImGui is designed and optimized to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Below is a screenshot from [LumixEngine](https://github.com/nem0/LumixEngine) with custom colors + a docking/tabs extension (both of which you can find in the Issues section and will eventually be merged):
+
+![LumixEngine](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v151/lumix-201710-rearranged.png)
+
+**Why using C++ (as opposed to C)?**
+
+Dear ImGui takes advantage of a few C++ languages features for convenience but nothing anywhere Boost-insanity/quagmire. Dear ImGui does NOT require C++11 so it can be used with most old C++ compilers. Dear ImGui doesn't use any C++ header file. Language-wise, function overloading and default parameters are used to make the API easier to use and code more terse. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors and templates (in the case of the ImVector<> class) are also relied on as a convenience.
+
+There is an auto-generated [c-api for Dear ImGui (cimgui)](https://github.com/cimgui/cimgui) by Sonoro1234 and Stephan Dilly. It is designed for creating binding to other languages. If possible, I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for various third-party bindings.

+Developed by [Omar Cornut](http://www.miracleworld.net) and every direct or indirect contributors to the GitHub. The early version of this library was developed with the support of [Media Molecule](http://www.mediamolecule.com) and first used internally on the game [Tearaway](http://tearaway.mediamolecule.com).
+
+I first discovered the IMGUI paradigm at [Q-Games](http://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it.

  - misc: provide a way to compile out the entire implementation while providing a dummy API (e.g. #define IMGUI_DUMMY_IMPL)
- - misc: provide HoveredTime and ActivatedTime to ease the creation of animations.
- - misc: fix for compilation settings where stdcall isn't the default (e.g. vectorcall) (#1230)

+ - backend: bgfx? https://gist.github.com/RichardGale/6e2b74bc42b3005e08397236e4be0fd0
+ - web/emscriptem: refactor some examples to facilitate integration with emscripten main loop system. (#1713, #336)
+ - web/emscriptem: with refactored examples, we could provide a direct imgui_impl_emscripten platform layer (see eg. https://github.com/floooh/sokol-samples/blob/master/html5/imgui-emsc.cc#L42)
+
  - remote: make a system like RemoteImGui first-class citizen/project (#75)

  - optimization: replace vsnprintf with stb_printf? or enable the defines/infrastructure to allow it (#1038)
  - optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request.
  - optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335)
+ - optimization: fully covered window (covered by another with non-translucent bg + WindowRounding worth of padding) may want to clip rendering.
  - optimization: use another hash function than crc32, e.g. FNV1a
  - optimization/render: merge command-lists with same clip-rect into one even if they aren't sequential? (as long as in-between clip rectangle don't overlap)?
  - optimization: turn some the various stack vectors into statically-sized arrays

-Third party languages and frameworks bindings: https://github.com/ocornut/imgui/wiki/Links

-(extras: RemoteImGui, ImWindow, imgui_wm..)
+Dear ImGui is highly portable and only requires a few things to run and render:
 
-TL;DR; 
- - Newcomers, read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup ImGui in your codebase.
- - If you are using of the backend provided here, so you can copy the imgui_impl_xxx.cpp/h files
-   to your project and use them unmodified.
- - To LEARN how the library is setup, you may refer to 'opengl2_example' because is the simplest one to read.
-   However, do NOT USE the 'opengl2_example' if your code is using any modern GL3+ calls.
-   Mixing old fixed-pipeline OpenGL2 and modern OpenGL3+ is going to make everything more complicated.
-   Read comments below for details. If you are not sure, in doubt, use 'opengl3_example'.
- - If you have your own engine, you probably want to read a few of the examples first then adapt it to
-   your engine. Please note that if your engine is based on OpenGL/DirectX you can perfectly use the
-   existing rendering backends, don't feel forced to rewrite them with your own engine API, or you can
-   do that later when you already got things to work.
-
-ImGui is highly portable and only requires a few things to run:
  - Providing mouse/keyboard inputs
- - Load the font atlas texture into graphics memory
+ - Uploading the font atlas texture into graphics memory
  - Providing a render function to render indexed textured triangles
  - Optional: clipboard support, mouse cursor supports, Windows IME support, etc.
-So this is essentially what those examples are doing + the obligatory cruft for portability.
 
-Unfortunately in 2016 it is still tedious to create and maintain portable build files using external 
-libraries (the kind we're using here to create a window and render 3D triangles) without relying on 
-third party software. For most examples here I choose to provide:
- - Makefiles for Linux/OSX
- - Batch files for Visual Studio 2008+
- - A .sln project file for Visual Studio 2010+ 
-Please let me know if they don't work with your setup!
-You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
-directly with a command-line compiler.
+This is essentially what the example bindings in this folder are providing + obligatory portability cruft.
 
-ImGui has zero frame of lag for most behaviors and one frame of lag for some behaviors. 
-At 60 FPS your experience should be pleasant. Consider that OS mouse cursors are typically drawn through 
-a specific hardware accelerated route and may feel smoother than other GPU rendered contents. You may 
-experiment with the io.MouseDrawCursor flag to request ImGui to draw a mouse cursor itself, to visualize 
-the lag between a hardware cursor and a software cursor. It might be beneficial to the user experience
-to switch to a software rendered cursor when an interactive drag is in progress. 
-Also note that some setup or GPU drivers may be causing extra lag (possibly by enforcing triple buffering), 
-leaving you with no option but sadness/anger (Intel GPU drivers were reported as such).
+It is important to understand the difference between the core Dear ImGui library (files in the root folder)
+and examples bindings which we are describing here (examples/ folder).
+You should be able to write bindings for pretty much any platform and any 3D graphics API. With some extra
+effort you can even perform the rendering remotely, on a different machine than the one running the logic.
 
-opengl2_example/
-    *DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL*
-    GLFW + OpenGL example (old, fixed graphic pipeline).
-    This is mostly provided as a reference to learn how ImGui integration works, because it is easier to read.
-    If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything
-    more complicated, will require your code to reset every single OpenGL attributes to their initial state,
-    and might confuse your GPU driver. Prefer using opengl3_example.
+This folder contains two things:
 
-opengl3_example/
-    GLFW + OpenGL example (programmable pipeline, binding modern functions with GL3W).
-    This uses more modern OpenGL calls and custom shaders. 
-    Prefer using that if you are using modern OpenGL3/4 in your application.
+ - Example bindings for popular platforms/graphics API, which you can use as is or adapt for your own use.
+   They are the imgui_impl_XXXX files found in the examples/ folder.
 
-directx9_example/
+ - Example applications (standalone, ready-to-build) using the aforementioned bindings.
+   They are the in the XXXX_example/ sub-folders.
+
+You can find binaries of some of those example applications at:

+
+
+---------------------------------------
+ MISC COMMENTS AND SUGGESTIONS
+---------------------------------------
+
+ - Please read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
+   Please read the comments and instruction at the top of each file.
+
+ - If you are using of the backend provided here, so you can copy the imgui_impl_xxx.cpp/h files
+   to your project and use them unmodified. Each imgui_impl_xxxx.cpp comes with its own individual
+   ChangeLog at the top of the .cpp files, so if you want to update them later it will be easier to
+   catch up with what changed.
+
+ - Dear ImGui has 0 to 1 frame of lag for most behaviors, at 60 FPS your experience should be pleasant.
+   However, consider that OS mouse cursors are typically drawn through a specific hardware accelerated path
+   and will feel smoother than common GPU rendered contents (including Dear ImGui windows).
+   You may experiment with the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor itself,
+   to visualize the lag between a hardware cursor and a software cursor. However, rendering a mouse cursor
+   at 60 FPS will feel slow. It might be beneficial to the user experience to switch to a software rendered
+   cursor only when an interactive drag is in progress.
+   Note that some setup or GPU drivers are likely to be causing extra lag depending on their settings.
+   If you feel that dragging windows feels laggy and you are not sure who to blame: try to build an
+   application drawing a shape directly under the mouse cursor.
+
+
+---------------------------------------
+ EXAMPLE BINDINGS
+---------------------------------------
+
+Most the example bindings are split in 2 parts:
+
+ - The "Platform" bindings, in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, windowing.
+   Examples: Windows (imgui_impl_win32.cpp), GLFW (imgui_impl_glfw.cpp), SDL2 (imgui_impl_sdl.cpp)
+
+ - The "Renderer" bindings, in charge of: creating the main font texture, rendering imgui draw data.
+   Examples: DirectX11 (imgui_impl_dx11.cpp), GL3 (imgui_impl_opengl3.cpp), Vulkan (imgui_impl_vulkan.cpp)
+
+ - The example _applications_ usually combine 1 platform + 1 renderer binding to create a working program.
+   Examples: the example_win32_directx11/ application combines imgui_impl_win32.cpp + imgui_impl_dx11.cpp.
+
+ - Some bindings for higher level frameworks carry both "Platform" and "Renderer" parts in one file.
+   This is the case for Allegro 5 (imgui_impl_allegro5.cpp), Marmalade (imgui_impl_marmalade5.cpp).
+
+ - If you use your own engine, you may decide to use some of existing bindings and/or rewrite some using
+   your own API. As a recommendation, if you are new to Dear ImGui, try using the existing binding as-is
+   first, before moving on to rewrite some of the code. Although it is tempting to rewrite both of the
+   imgui_impl_xxxx files to fit under your coding style, consider that it is not necessary!
+   In fact, if you are new to Dear ImGui, rewriting them will almost always be harder.
+
+   Example: your engine is built over Windows + DirectX11 but you have your own high-level rendering
+   system layered over DirectX11.
+     Suggestion: step 1: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first.
+     Once this work, _if_ you want you can replace the imgui_impl_dx11.cpp code with a custom renderer
+     using your own functions, etc.
+     Please consider using the bindings to the lower-level platform/graphics API as-is.
+
+   Example: your engine is multi-platform (consoles, phones, etc.), you have high-level systems everywhere.
+     Suggestion: step 1: try using a non-portable binding first (e.g. win32 + underlying graphics API)!
+     This is counter-intuitive, but this will get you running faster! Once you better understand how imgui
+     works and is bound, you can rewrite the code using your own systems.
+
+ - Road-map: Dear ImGui 1.70 (WIP currently in the "viewport" branch) will allows imgui windows to be
+   seamlessly detached from the main application window. This is achieved using an extra layer to the
+   platform and renderer bindings, which allows imgui to communicate platform-specific requests.
+   If you decide to use unmodified imgui_impl_xxxx.cpp files, you will automatically benefit from
+   improvements and fixes related to viewports and platform windows without extra work on your side.

-# iOS / OSX example
-
-## Introduction
-
-This example is the default XCode "OpenGL" example code, modified to support ImGui and [Synergy](http://synergy-project.org/) to share mouse/keyboard on an iOS device.
-
-It is a rather complex and messy example because of all of the faff required to get an XCode/iOS application running. Refer to the regular OpenGL examples if you want to learn about integrating ImGui. **The opengl3_example/ should also work on OS X and is much simpler.** This is an integration for iOS with Synergy.
-
-Synergy (remote keyboard/mouse) is not required, but it's pretty hard to use ImGui without it. Synergy includes a "uSynergy" library that allows embedding a synergy client, this is what is used here. ImGui supports "TouchPadding", and this is enabled when Synergy is not active.
-
-## How to Use on iOS
-
-* In Synergy, go to Preferences, and uncheck "Use SSL encryption"
-* Run the example app.
-* Tap the "servername" button in the corner
-* Enter the name or the IP of your synergy host
-* If you had previously connected to a server, you may need to kill and re-start the app.
-
-## How to Build on OSX
-
-* Make sure you have install `brew`, if not, please refer to [Homebrew Website](http://brew.sh)
-* Run the command: `brew install glfw3`
-* Double click `imguiex.xcodeproj` and select `imguiex-osx` scheme
-* Click `Run` button
-
-## Notes and TODOs
-
-Things that would be nice but I didn't get around to doing:
-
-* iOS software keyboard not supported for text inputs
-* iOS hardware (bluetooth) keyboards not supported
-* Graceful disconnect/reconnect from uSynergy.
-* Copy/Paste not well-supported
-
-## C++ on iOS / OSX
-
-ImGui is a c++ library. If you want to include it directly, rename your Obj-C file to have the ".mm" extension. 
-
-Alternatively, you can wrap your debug code in a C interface, this is what I am demonstrating here with the "debug_hud.h" interface. Either approach works, use whatever you prefer.
-
-In my case, most of my game code is already in C++ so it's not really an issue and I can use ImGui directly.

+# Configuration
+
+Dear ImGui outputs 16-bit vertex indices by default. 
+Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile imgui with 32-bit indices.
+You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename.
+We are providing `imconfig_allegro5.h` that enables 32-bit indices.
+Note that the back-end supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.
+
+# How to Build
