-// - A third-party Emscripten GLFW (3.4.0) implementation (syntax: "--use-port=contrib.glfw3") fixes the Joystick issue and implements all relevant features for the browser.
-// See https://github.com/pongasoft/emscripten-glfw/blob/master/docs/Comparison.md for details.
-
 // CHANGELOG
 // (minor and older changes stripped away, please see git history for details)
-//  2024-08-22: moved some OS/backend related function pointers from ImGuiIO to ImGuiPlatformIO:
-//               - io.GetClipboardTextFn    -> platform_io.Platform_GetClipboardTextFn
-//               - io.SetClipboardTextFn    -> platform_io.Platform_SetClipboardTextFn
-//               - io.PlatformOpenInShellFn -> platform_io.Platform_OpenInShellFn
-//  2024-07-31: Added ImGui_ImplGlfw_Sleep() helper function for usage by our examples app, since GLFW doesn't provide one.
-//  2024-07-08: *BREAKING* Renamed ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback to ImGui_ImplGlfw_InstallEmscriptenCallbacks(), added GLFWWindow* parameter.
-//  2024-07-08: Emscripten: Added support for GLFW3 contrib port (GLFW 3.4.0 features + bug fixes): to enable, replace -sUSE_GLFW=3 with --use-port=contrib.glfw3 (requires emscripten 3.1.59+) (https://github.com/pongasoft/emscripten-glfw)
-//  2024-07-02: Emscripten: Added io.PlatformOpenInShellFn() handler for Emscripten versions.
 //  2023-12-19: Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to register canvas selector and auto-resize GLFW window.
 //  2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys.
 //  2023-07-18: Inputs: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFLags_NoMouse if desired. (#5625, #6609)

- VERSION 1.91.4 (Released 2024-10-18)
+ VERSION 1.90.9 WIP (In Progress)
 -----------------------------------------------------------------------
 
 Breaking changes:
 
-- Style: renamed ImGuiCol_NavHighlight to ImGuiCol_NavCursor, for consistency with 
-  newly exposed and reworked features. Kept inline redirection enum (will obsolete).
-- The typedef for ImTextureID now defaults to ImU64 instead of void*. (#1641)
-  - This removes the requirement to redefine it for backends which are e.g. storing
-    descriptor sets or other 64-bits structures when building on 32-bits archs
-    (namely our DX12 and Vulkan backends). It therefore simplify various building scripts/helpers.
-  - You may have compile-time warnings if you were casting to 'void*' instead of 'ImTextureID'
-    when passing your types to functions taking ImTextureID values, e.g. ImGui::Image().
-    In doubt it is almost always better to do an intermediate intptr_t cast, since it
-    allows casting any pointer/integer type without warning:
-    - May warn:     ImGui::Image((void*)MyTextureData, ...);
-    - May warn:     ImGui::Image((void*)(intptr_t)MyTextureData, ...);
-    - Won't warn:   ImGui::Image((ImTextureID)(intptr_t)MyTextureData), ...);
-  - Note that you can always define ImTextureID to be your own high-level structures
-    (with dedicated constructors and extra render parameters) if you like.
-- IO: moved ImGuiConfigFlags_NavEnableSetMousePos to standalone io.ConfigNavMoveSetMousePos bool.
-- IO: moved ImGuiConfigFlags_NavNoCaptureKeyboard to standalone io.ConfigNavCaptureKeyboard bool 
-  (note the inverted value!). (#2517, #2009)
-  Kept legacy names (will obsolete) + code that copies settings once the first time. 
-  Dynamically changing the old value won't work. Switch to using the new value!
-
 Other changes:
 
-- IO: added 'void* platform_io.Renderer_RenderState' which is set during the
-  ImGui_ImplXXXX_RenderDrawData() of standard backends to expose selected render
-  states to your draw callbacks. (#6969, #5834, #7468, #3590)
-- IO: io.WantCaptureKeyboard is never set when ImGuiConfigFlags_NoKeyboard is enabled. (#4921)
-- Error Handling: turned a few more functions into recoverable errors. (#1651)
-- Nav (Keyboard/Gamepad navigation):
-  - Nav: added io.ConfigNavCursorVisibleAuto and io.ConfigNavCursorVisibleAlways to configure
-    visibility of navigation cursor. (#1074, #2048, #7237, #8059, #3200, #787)
-     - Set io.ConfigNavCursorVisibleAuto = true (default) to enable automatic toggling
-       of cursor visibility (mouse click hide the cursor, arrow keys makes it visible).
-     - Set io.ConfigNavCursorVisibleAlways to keep cursor always visible.
-  - Nav: added NavSetCursorVisible(bool visible) function to manipulate visibility of 
-    navigation cursor (e.g. set default state, or after some actions). (#1074, #2048, #7237, #8059)
-  - Nav: added io.ConfigNavEscapeClearFocusItem and io.ConfigNavEscapeClearFocusWindow to change
-    how pressing Escape affects navigation. (#8059, #2048, #1074, #3200)
-    - Set io.ConfigNavEscapeClearFocusItem = true (default) to clear focused item and highlight.
-    - Set io.ConfigNavEscapeClearFocusItem = false for Escape to not have an effect.
-    - Set io.ConfigNavEscapeClearFocusWindow = true to completely unfocus the dear imgui window,
-      is for some reason your app relies on imgui focus to take other decisions.  
-  - Nav: pressing escape to hide the navigation cursor doesn't clear location, so it may be
-    restored when Ctrl+Tabbing back into the same window later.
-  - Nav: fixed Ctrl+Tab initiated with no focused window from skipping the top-most window. (#3200)
-  - Nav: navigation cursor is not rendered for items with `ImGuiItemFlags_NoNav`. Can be relevant 
-    when e.g activating a _NoNav item with mouse, then Ctrl+Tabbing back and forth.
-- Disabled: clicking a disabled item focuses parent window. (#8064) 
-- InvisibleButton, Nav: fixed an issue when InvisibleButton() would be navigable into but
-  not display navigation highlight. Properly navigation on it by default. (#8057)
-- InvisibleButton: added ImGuiButtonFlags_EnableNav to enable navigation. (#8057)
-- Tooltips: fixed incorrect tooltip positioning when using keyboard/gamepad navigation 
-  (1.91.3 regression). (#8036)
-- DrawList: AddCallback() added an optional size parameter allowing to copy and
-  store any amount of user data for usage by callbacks: (#6969, #4770, #7665)
-  - If userdata_size == 0: we copy/store the 'userdata' argument as-is (existing behavior).
-    It will be available unmodified in ImDrawCmd::UserCallbackData during render.
-  - If userdata_size > 0, we copy/store 'userdata_size' bytes pointed to by 'userdata' (new behavior).
-    We store them in a buffer stored inside the drawlist. ImDrawCmd::UserCallbackData 
-    will point inside that buffer so you have to retrieve data from there. Your callback
-    may need to use ImDrawCmd::UserCallbackDataSize if you expect dynamically-sized data.
-  - Note that we use a raw type-less copy.
-- Tables: fixed initial auto-sizing issue with synced-instances. (#8045, #7218)
-- InputText: fixed an issue with not declaring ownership of Delete/Backspace/Arrow keys,
-  preventing use of external shortcuts that are not guarded by an ActiveId check. (#8048) 
-  [@geertbleyen]
-- InputText: ensure mouse cursor shape is set regardless of whether keyboard mode is 
-  enabled or not. (#6417)
-- InputScalar: added an assert to clarify that ImGuiInputTextFlags_EnterReturnsTrue is not
-  supported by InputFloat, InputInt, InputScalar etc. widgets. It actually never was. (#8065, #3946)
-- imgui_freetype: Added support for plutosvg (as an alternative to lunasvg) to render 
-  OpenType SVG fonts. Requires defining IMGUI_ENABLE_FREETYPE_PLUTOSVG along with IMGUI_ENABLE_FREETYPE.
-  Providing headers/librairies for plutosvg + plutovg is up to you (see #7927 for help).
-  (#7927, #7187, #6591, #6607) [@pthom]

-Breaking changes:
-
-- Drags: treat v_min==v_max as a valid clamping range when != 0.0f. Zero is still a special
-  value due to legacy reasons, unless using ImGuiSliderFlags_ClampZeroRange. (#7968, #3361, #76)
-- Drags: extended behavior of ImGuiSliderFlags_AlwaysClamp to include _ClampZeroRange.
-  It considers v_min==v_max==0.0f as a valid clamping range (aka edits not allowed).
-  Although unlikely, it you wish to only clamp on text input but want v_min==v_max==0.0f
-  to mean unclamped drags, you can use _ClampOnInput instead of _AlwaysClamp. (#7968, #3361, #76)
-
-Other changes:
-
-- Error Handling: Enabled/improved error recovery systems. (#1651, #5654)
-  - Error recovery is provided as a way to facilitate:
-    - Recovery after a programming error. Native code or scripting language (the later
-      tends to facilitate iterating on code while running).
-    - Recovery after running an exception handler or any error processing which may skip code
-      after an error has been detected.
-  - Error recovery is not perfect nor guaranteed! It is a feature to ease development.
-    You not are not supposed to rely on it in the course of a normal application run.
-  - Functions that support error recovery are using IM_ASSERT_USER_ERROR() instead of IM_ASSERT().
-  - By design, we do not allow error recovery to be 100% silent. One of the options needs to be enabled!
-  - Possible usage: facilitate recovery from errors triggered from a scripting language or
-    after specific exceptions handlers. Surface errors to programmers in less aggressive ways.
-  - Always ensure that on programmers seats you have at minimum Asserts or Tooltips enabled
-    when making direct imgui API calls! Otherwise it would severely hinder your ability to
-    catch and correct mistakes!
-  - Added io.ConfigErrorRecovery to enable error recovery support.
-  - Added io.ConfigErrorRecoveryEnableAssert to assert on recoverable errors.
-  - Added io.ConfigErrorRecoveryEnableDebugLog to output to debug log on recoverable errors.
-  - Added io.ConfigErrorRecoveryEnableTooltip to enable displaying an error tooltip on recoverable errors.
-    The tooltip include a way to enable asserts if they were disabled.
-  - All options are enabled by default.
-  - Read https://github.com/ocornut/imgui/wiki/Error-Handling for a bit more details.
-- Windows: BeginChild(): made it possible to call SetNextWindowSize() on a child window
-  using ImGuiChildFlags_ResizeX,ImGuiChildFlags_ResizeY in order to override its current
-  size. (#1710, #8020)
-- Scrollbar: Shift+Click scroll to clicked location (pre-1.90.8 default). (#8002, #7328)
-- Scrollbar: added io.ConfigScrollbarScrollByPage setting (default to true). (#8002, #7328)
-  Set io.ConfigScrollbarScrollByPage=false to enforce always scrolling to clicked location.
-- Drags: split ImGuiSliderFlags_AlwaysClamp into two distinct flags: (#7968, #3361, #76)
-  - ImGuiSliderFlags_AlwaysClamp = ImGuiSliderFlags_ClampOnInput + ImGuiSliderFlags_ClampZeroRange.
-  - Previously _AlwaysClamp only did the equivalent of _ClampOnInput.
-  - Added ImGuiSliderFlags_ClampOnInput which is now a subset of AlwaysClamp.
-    (note that it was the old name of AlwaysClamp, but we are reintroducing that name).
-  - Added ImGuiSliderFlags_ClampZeroRange to enforce clamping even when v_min==v_max==0.0f
-    in drag functions. Sliders are not affected.
-- Tooltips, Drag and Drop: Fixed an issue where the fallback drag and drop payload tooltip
-  appeared during drag and drop release.
-- Tooltips, Drag and Drop: Stabilized name of drag and drop tooltip window so that
-  transitioning from an item tooltip to a drag tooltip doesn't leak window auto-sizing
-  info from one to the other. (#8036)
-- Tooltips: Tooltips triggered from touch inputs are positioned above the item. (#8036)
-- Backends: SDL3: Update for API changes: SDL_bool removal. SDL_INIT_TIMER removal.
-- Backends: WebGPU: Fixed DAWN api change using WGPUStringView in WGPUShaderSourceWGSL.

- - Internals: using multiple overlayed ButtonBehavior() with same ID will now have the
-   io.ConfigDebugHighlightIdConflicts=true feature emit a warning. (#8030)
-   It was one of the rare case where using same ID is legal. Workarounds:
-   - use single ButtonBehavior() call with multiple _MouseButton flags
-   - or surround the calls with PushItemFlag(ImGuiItemFlags_AllowDuplicateId, true); ... PopItemFlag()
-
-Other changes:
-
-- Added io.ConfigDebugHighlightIdConflicts debug feature! (#7961, #7669)
-  THIS DETECTS THE MOST COMMON USER ERROR BY FIRST-TIME DEAR IMGUI PROGRAMMERS!
-  - The tool detects when multiple items are sharing the same identifier, due to not
-    using PushID/PopID in loops, or not using ID stack facilities such as "##" suffixes.
-    Very frequently it happens when using empty "" labels.
-  - When hovering an item with a conflicting ID, all visible items with the same ID will
-    be highlighted and an explanatory tooltip is made visible.
-  - The feature may be disabled and is exposed in Demo->Tools menu.
-  - I've been wanting to add this tool for a long time, but was stalled by finding a way to
-    not make it spammy + make it practically zero cost. After @pthom made various proposals to
-    solve the same problem (thanks for pushing me!), I decided it was time to finish it.
-  - Added ImGuiItemFlags_AllowDuplicateId to use with PushItemFlag()/PopItemFlag() if for some
-    reason you intend to have duplicate identifiers.

-- Inputs: SetNextItemShortcut() with ImGuiInputFlags_Tooltip doesn't show tooltip when item is active.
-- InputText: internal refactoring to simplify and optimize the code. The ImWchar buffer has been
-  removed. Simplifications allowed to implement new optimizations for handling very large text buffers

-    - io.PlatformOpenInShellFn      -> platform_io.Platform_OpenInShellFn (#7660)
-    - io.PlatformSetImeDataFn       -> platform_io.Platform_SetImeDataFn
-    - io.PlatformLocaleDecimalPoint -> platform_io.Platform_LocaleDecimalPoint (#7389, #6719, #2278)
-    - access those via GetPlatformIO() instead of GetIO().
-  (Because PlatformOpenInShellFn and PlatformSetImeDataFn were introduced very recently and
-  often automatically set by core library and backends, we are exceptionally not maintaining
-  a legacy redirection symbol for those two.)
-- Commented the old ImageButton() signature obsoleted in 1.89 (~August 2022). (#5533, #4471, #2464, #1390)
-   - old ImageButton() used ImTextureId as item id (created issue with e.g. multiple buttons in same scope, transient texture id values, opaque computation of ID)
-   - new ImageButton() requires an explicit 'const char* str_id'
-   - old ImageButton() had frame_padding' override argument.
-   - new ImageButton() always use style.FramePadding, which you can modify using PushStyleVar()/PopStyleVar().
-
-Other changes:
-
-- IO: Added GetPlatformIO() and ImGuiPlatformIO, pulled from 'docking' branch, which
-  is a centralized spot to connect os/platform/renderer related functions.
-  Clipboard, IME and OpenInShell hooks are moved here. (#7660)
-- IO, InputText: fixed an issue where typing text in an InputText() would defer character
-  processing by one frame, because of the trickling input queue. Reworked interleaved
-  keys<>char trickling to take account for keys known to input characters. (#7889, #4921, #4858)
-- Windows: adjust default ClipRect to better match rendering of thick borders (which are in
-  theory not supported). Compensate for the fact that borders are centered around the windows
-  edge rather than inner. (#7887, #7888 + #3312, #7540, #3756, #6170, #6365)
-- Made BeginItemTooltip() and IsItemHovered() with delay flag infer an implicit ID (for
-  ID-less items such as Text element) in a way that works when item resizes. (#7945, #1485)
-- MultiSelect+TreeNode+Drag and Drop: fixed an issue where carrying a drag and drop payload
-  over an already open tree node using multi-select would incorrectly select it. (#7850)
-- MultiSelect+TreeNode: default open behavior is _OpenOnDoubleClick + _OpenOnArrow when
-  used in a multi-select context without any ImGuiTreeNode_OpenOnXXX flags set. (#7850)
-- Tables: fixes/revert a 1.90 change were outer border would be moved bottom and right
-  by an extra pixel + rework the change so that contents doesn't overlap the bottom and
-  right border in a scrolling table. (#6765, #3752, #7428)
-- Tables: fixed an issue resizing columns or querying hovered column/row when using multiple
-  synched instances that are layed out at different X positions. (#7933)
-- Tabs: avoid queuing a refocus when tab is already focused, which would have the
-  side-effect of e.g. closing popup on a mouse release. (#7914)
-- InputText: allow callback to update buffer while in read-only mode. (imgui_club/#46)
-- InputText: fixed an issue programmatically refocusing a multi-line input which was just active. (#4761, #7870)
-- TextLink(), TextLinkOpenURL(): change mouse cursor to Hand shape when hovered. (#7885, #7660)
-- Tooltips, Drag and Drop: made it possible to override BeginTooltip() position while inside
-  a drag and drop source or target: a SetNextWindowPos() call won't be overridden. (#6973)
-- PlotHistogram, PlotLines: register item ID and use button behavior in a more idiomatic manner,
-  fixes preventing e.g. GetItemID() and other ID-based helper to work. (#7935, #3072)
-- Style: added PushStyleVarX(), PushStyleVarY() helpers to conveniently modify only
-  one component of a ImVec2 var.
-- Fonts: made it possible to use PushFont()/PopFont() calls across Begin() calls. (#3224, #3875, #6398, #7903)
-- Backends:
-  - Backends: GLFW: added ImGui_ImplGlfw_Sleep() helper function because GLFW does not
-    provide a way to do a portable sleep. (#7844)
-  - Backends: GLFW+Emscripten: Use OpenURL() from GLFW3 contrib port when available and using
-    the contrib port instead of Emscripten own GLFW3 implementation. (#7647, #7915, #7660) [@ypujante]
-  - Backends: SDL2, SDL3: ignore events of other SDL windows. (#7853) [@madebr, @ocornut]
-  - Backends: SDL2, SDL3: storing SDL_WindowID inside ImGuiViewport::PlatformHandle instead of SDL_Window*.
-  - Backends: SDL3: Update for API changes: SDL_GetGamepads() memory ownership logic was reverted back
-    by SDL3 on July 27. (#7918, #7898, #7807) [@cheyao, @MattGuerrette]
-  - Backends: GLFW: passing null window to glfwGetClipboardString()/glfwSetClipboardString()
-    since GLFW own tests are doing that and it seems unnecessary.
-  - Backends: SDL2, SDL3, GLFW, OSX, Allegro: update to set function handlers in ImGuiPlatformIO
-    instead of ImGuiIO.
-- Examples:
-  - Examples: GLFW (all), SDL2 (all), SDL3 (all), Win32+OpenGL3: rework examples main loop
-    to handle minimization without burning CPU or GPU by running unthrottled code. (#7844)
-  - Examples: SDL3: Update for API changes: SDL_Init() returns 0 on failure.

- VERSION 1.91.0 (Released 2024-07-30)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.91.0
-
-Breaking changes:
-
-- IO, IME: renamed platform IME hook and added explicit context for consistency and future-proofness.
-    - old: io.SetPlatformImeDataFn(ImGuiViewport* viewport, ImGuiPlatformImeData* data);
-    - new: io.PlatformSetImeDataFn(ImGuiContext* ctx, ImGuiViewport* viewport, ImGuiPlatformImeData* data);
-  It is expected that for a vast majority of users this is automatically set by core
-  library and/or platform backend so it won't have any effect.
-- Obsoleted GetContentRegionMax(), GetWindowContentRegionMin() and GetWindowContentRegionMax(). (#7838)
-  You should never need those functions! You can do everything in less a confusing manner by only
-  using GetCursorScreenPos() and GetContentRegionAvail(). Also always consider that if you are using
-  GetWindowPos() and GetCursorPos() you may also be making things unnecessarily complicated.
-  I repeat: You can do everything with GetCursorScreenPos() and GetContentRegionAvail()!
-   - GetWindowContentRegionMax().x - GetCursorPos().x              -->  GetContentRegionAvail().x
-   - GetWindowContentRegionMax().x + GetWindowPos().x              -->  GetCursorScreenPos().x + GetContentRegionAvail().x              // when called from left edge of window
-   - GetContentRegionMax()                                         -->  GetContentRegionAvail() + GetCursorScreenPos() - GetWindowPos() // right edge in local coordinates
-   - GetWindowContentRegionMax().x - GetWindowContentRegionMin().x -->  GetContentRegionAvail()                                         // when called from left edge of window
-- Item flag changes:
-  - Obsoleted PushButtonRepeat()/PopButtonRepeat() in favor of using new PushItemFlag()/PopItemFlag()
-    with ImGuiItemFlags_ButtonRepeat. Kept inline redirecting functions (will obsolete).
-  - Obsoleted PushTabStop()/PopTabStop() in favor of using new PushItemFlag()/PopItemFlag()
-    with ImGuiItemFlags_NoTabStop. Kept inline redirecting functions (will obsolete).
-  - Renamed ImGuiSelectableFlags_DontClosePopups to ImGuiSelectableFlags_NoAutoClosePopups for
-    consistency. Kept inline redirecting functions (will obsolete).
-    + Internals: changed/inverted ImGuiItemFlags_SelectableDontClosePopup (default==false) to
-      ImGuiItemFlags_AutoClosePopups (default==true), same logic, only inverted behavior.
-    (#1379, #1468, #2200, #4936, #5216, #7302, #7573)
-- Commented out obsolete ImGuiModFlags (renamed to ImGuiKeyChord in 1.89). (#4921, #456)
-- Commented out obsolete ImGuiModFlags_XXX values (renamed to ImGuiMod_XXX in 1.89). (#4921, #456)
-    - ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl, ImGuiModFlags_Shift -> ImGuiMod_Shift etc.
-- Backends: GLFW+Emscripten: Renamed ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to
-  ImGui_ImplGlfw_InstallEmscriptenCallbacks(), with an additional GLFWWindow* parameter. (#7647) [@ypujante]
-
-Other changes:
-
-- Added TextLink(), TextLinkOpenURL() hyperlink widgets. (#7660)
-- IO: added io.PlatformOpenInShellFn handler to open a link/folder/file in OS shell. (#7660)
-  (*EDIT* From next version 1.91.1 we moved this to platform_io.Platform_OpenInShellFn *EDIT**)
-  Added IMGUI_DISABLE_DEFAULT_SHELL_FUNCTIONS to disable default Windows/Linux/Mac implementations.
-- IO: added io.ConfigNavSwapGamepadButtons to swap Activate/Cancel (A<>B) buttons, to match the
-  typical "Nintendo/Japanese consoles" button layout when using Gamepad navigation. (#787, #5723)
-- Added PushItemFlag()/PopItemFlags(), ImGuiItemFlags to modify shared item flags:
-   - Added ImGuiItemFlags_NoTabStop to disable tabbing through items.
-   - Added ImGuiItemFlags_NoNav to disable any navigation and focus of items. (#787)
-   - Added ImGuiItemFlags_NoNavDefaultFocus to disable item being default focus. (#787)
-   - Added ImGuiItemFlags_ButtonRepeat to enable repeat on any button-like behavior.
-   - Added ImGuiItemFlags_AutoClosePopups to disable menu items/selection auto closing parent popups.
-     Disabling this was previously possible for Selectable() via a direct flag but not for MenuItem().
-     (#1379, #1468, #2200, #4936, #5216, #7302, #7573)
-   - This was mostly all previously in imgui_internal.h.
-- Multi-Select: added multi-select API and demos. (#1861, #6518)
-   - This system implements standard multi-selection idioms (CTRL+mouse click, CTRL+keyboard moves,
-     SHIFT+mouse click, SHIFT+keyboard moves, etc.) with support for clipper (not submitting non-visible
-     items), box-selection with scrolling, and many other details.
-   - In the spirit of Dear ImGui design, your code owns both items and actual selection data.
-     This is designed to allow all kinds of selection storage you may use in your application
-     (e.g. set/map/hash, intrusive selection, interval trees, up to you).
-   - The supported widgets are Selectable(), Checkbox(). TreeNode() is also technically supported but...
-     using this correctly is more complicated. You need some sort of linear/random access to your tree,
-     which is suited to advanced trees setups already implementing filters and clipper.
-     We will work toward simplifying our existing demo for trees.
-   - A helper ImGuiSelectionBasicStorage is provided to facilitate getting started in a typical app
-     (likely to suit a majority of users).
-   - Documentation:
-     - Wiki page https://github.com/ocornut/imgui/wiki/Multi-Select for API overview.
-     - Demo code + headers are well commented.
-  - Added BeginMultiSelect(), EndMultiSelect(), SetNextItemSelectionUserData().
-  - Added IsItemToggledSelection() for use if you need latest selection update during current iteration.
-  - Added ImGuiMultiSelectIO and ImGuiSelectionRequest structures:
-    - BeginMultiSelect() and EndMultiSelect() return a ImGuiMultiSelectIO structure, which
-      is mostly an array of ImGuiSelectionRequest actions (clear, select all, set range, etc.)
-    - Other fields are helpful when using a clipper, or wanting to handle deletion nicely.
-  - Added ImGuiSelectionBasicStorage helper to store and maintain a selection (optional):
-    - This is similar to if you used e.g. a std::set<ID> to store a selection, with all the right
-      glue to honor ImGuiMultiSelectIO requests. Most applications can use that.
-  - Added ImGuiSelectionExternalStorage helper to maintain an externally stored selection (optional):
-    - Helpful to easily bind multi-selection to e.g. an array of checkboxes.
-  - Added ImGuiMultiSelectFlags options:
-    - ImGuiMultiSelectFlags_SingleSelect
-    - ImGuiMultiSelectFlags_NoSelectAll
-    - ImGuiMultiSelectFlags_NoRangeSelect
-    - ImGuiMultiSelectFlags_NoAutoSelect
-    - ImGuiMultiSelectFlags_NoAutoClear
-    - ImGuiMultiSelectFlags_NoAutoClearOnReselect (#7424)
-    - ImGuiMultiSelectFlags_BoxSelect1d
-    - ImGuiMultiSelectFlags_BoxSelect2d
-    - ImGuiMultiSelectFlags_BoxSelectNoScroll
-    - ImGuiMultiSelectFlags_ClearOnEscape
-    - ImGuiMultiSelectFlags_ClearOnClickVoid
-    - ImGuiMultiSelectFlags_ScopeWindow (default), ImGuiMultiSelectFlags_ScopeRect
-    - ImGuiMultiSelectFlags_SelectOnClick (default), ImGuiMultiSelectFlags_SelectOnClickRelease
-    - ImGuiMultiSelectFlags_NavWrapX
-  - Demo: Added "Examples->Assets Browser" demo.
-  - Demo: Added "Widgets->Selection State & Multi-Select" section, with:
-    - Multi-Select
-    - Multi-Select (with clipper)
-    - Multi-Select (with deletion)
-    - Multi-Select (dual list box) (#6648)
-    - Multi-Select (in a table)
-    - Multi-Select (checkboxes)
-    - Multi-Select (multiple scopes)
-    - Multi-Select (tiled assert browser)
-    - Multi-Select (trees) (#1861)
-    - Multi-Select (advanced)
-- Inputs: added SetItemKeyOwner(ImGuiKey key) in public API.
-  This is a simplified version of a more complete set of function available in imgui_internal.h.
-  One common use-case for this is to allow your widgets to disable standard inputs behaviors such
-  as Tab or Alt handling, Mouse Wheel scrolling, etc.
-  (#456, #2637, #2620, #2891, #3370, #3724, #4828, #5108, #5242, #5641)
-     // Hovering or activating the button will disable mouse wheel default behavior to scroll
-     InvisibleButton(...);
-     SetItemKeyOwner(ImGuiKey_MouseWheelY);
-- Nav: fixed clicking window decorations (e.g. resize borders) from losing focused item when
-  within a child window using ImGuiChildFlags_NavFlattened.
-- InputText: added '\' and '/' as word separator. (#7824, #7704) [@reduf]
-- TreeNode: added SetNextItemStorageID() to specify/override the identifier used for persisting
-  open/close storage. Useful if needing to often read/write from storage without manipulating
-  the ID stack. (#7553, #6990, #3823, #1131)
-- Selectable: added ImGuiSelectableFlags_Highlight flag to highlight items independently from
-  the hovered state. (#7820) [@rerilier]
-- Clipper: added SeekCursorForItem() function. When using ImGuiListClipper::Begin(INT_MAX) you can
-  can use the clipper without knowing the amount of items beforehand. (#1311)
-  In this situation, call ImGuiListClipper::SeekCursorForItem(items_count) at the end of your iteration
-  loop to position the layout cursor correctly. This is done automatically if provided a count to Begin().
-- Groups, Tables: fixed EndGroup() failing to correctly capture current table occupied size. (#7543)
-- Style, TabBar: added style.TabBarOverlineSize / ImGuiStyleVar_TabBarOverlineSize to manipulate
-  thickness of the horizontal line over selected tabs. [@DctrNoob]
-- Style: close button and collapse/window-menu button hover highlight made rectangular instead of round.
-- Misc: added GetID(int) variant for consistency. (#7111)
-- Debug Tools:
-  - Debug Log: Added IMGUI_DEBUG_LOG(), ImGui::DebugLog() in public API. (#5855)
-    Printed entries include imgui frame counter prefix + are redirected to ShowDebugLogWindow() and
-    other configurable locations. Always call IMGUI_DEBUG_LOG() for maximum stripping in caller code.
-  - Debug Log: Added "Configure Outputs.." button. (#5855)
-  - Debug Log: Fixed incorrect checkbox layout when partially clipped.
-- Demo: Reworked "Property Editor" demo in a manner that more resemble the tree data and
-  struct description data that a real application would want to use.
-- Backends:
-  - Backends: Win32: Fixed ImGuiMod_Super being mapped to VK_APPS instead of (VK_LWIN || VK_RWIN).
-    (#7768, #4858, #2622) [@Aemony]
-  - Backends: SDL3: Update for API changes: SDL_GetGamepads() memory ownership change. (#7807)
-  - Backends: SDL3: Update for API changes: SDL_GetClipboardText() memory ownership change. (#7801)
-  - Backends: SDL3: Update for API changes: SDLK_x renames and SDLK_KP_x removals (#7761, #7762)
-  - Backends: SDL3: Update for API changes: SDL_GetProperty() change to SDL_GetPointerProperty(). (#7794) [@wermipls]
-  - Backends: SDL2,SDL3,OSX: Update for io.SetPlatformImeDataFn() -> io.PlatformSetImeDataFn() rename.
-  - Backends: GLFW,SDL2: Added io.PlatformOpenInShellFn handler for web/Emscripten versions. (#7660)
-    [@ypujante, @ocornut]
-  - Backends: GLFW+Emscripten: Added support for GLFW3 contrib port which fixes many of the things
-    not supported by the embedded GLFW: gamepad support, mouse cursor shapes, copy to clipboard,
-    workaround for Super/Meta key, different ways of resizing, multi-window (glfw/canvas) support.
-    (#7647) [@ypujante]
-  - Backends: GLFW+Emscripten: Fixed Emscripten warning when using mouse wheel on some setups
-    "Unable to preventDefault inside passive event listener". (#7647, #7600) [@ypujante]

- VERSION 1.90.9 (Released 2024-07-01)
------------------------------------------------------------------------
-
-Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.9
-
-Breaking changes:
-
-- Removed old nested structure: renaming ImGuiStorage::ImGuiStoragePair type to
-  ImGuiStoragePair (simpler for many languages). No significant nested type left.
-- BeginChild: added ImGuiChildFlags_NavFlattened as a replacement for the window
-  flag ImGuiWindowFlags_NavFlattened: the feature only ever made sense for
-  BeginChild() calls anyhow. (#7687) [@cfillion]
-   - old: BeginChild("Name", size, 0, ImGuiWindowFlags_NavFlattened);
-   - new: BeginChild("Name", size, ImGuiChildFlags_NavFlattened, 0)
-  Kept inline redirection flag (will obsolete).
-- Style: renamed tab colors for clarity and consistency with other changes: (#261, #351)
-  - ImGuiCol_TabActive          -> ImGuiCol_TabSelected
-  - ImGuiCol_TabUnfocused       -> ImGuiCol_TabDimmed
-  - ImGuiCol_TabUnfocusedActive -> ImGuiCol_TabDimmedSelected
-  Kept inline redirecting enums (will obsolete).
-- IO: io.ClearInputKeys() (first exposed in 1.89.8) doesn't clear mouse data.
-  Newly added io.ClearInputMouse() does. (#4921)
-- Drag and Drop: renamed ImGuiDragDropFlags_SourceAutoExpirePayload to
-  ImGuiDragDropFlags_PayloadAutoExpire. Kept inline redirecting enum (will obsolete). (#1725, #143)
-
-Other changes:
-
-- IO: do not disable io.ConfigWindowsResizeFromEdges (which allow resizing from borders
-  and lower-left corner) when ImGuiBackendFlags_HasMouseCursors is not set by backend.
-  The initial reasoning is that resizing from borders feels better when correct mouse cursor
-  shape change as honored by backends. Keeping this enabling will hopefully increase pressure
-  on third-party backends to set ImGuiBackendFlags_HasMouseCursors and honor changes of
-  ImGui::GetMouseCursor() value. (#1495)
-- IO: do not claim io.WantCaptureMouse=true on the mouse release frame of a button
-  which was pressed over void/underlying app, which is consistent/needed to allow the
-  mouse up event of a drag over void/underlying app to catch release. (#1392) [@Moka42]
-- IO: Added io.ClearInputMouse() to clear mouse state. (#4921)
-- IO: Added ImGuiConfigFlags_NoKeyboard for consistency and convenience. (#4921)
-- Windows: BeginChild(): fixed a glitch when during a resize of a child window which is
-  tightly close to the boundaries of its parent (e.g. with zero WindowPadding), the child
-  position could have temporarily be moved around by erroneous padding application. (#7706)
-- TabBar, Style: added ImGuiTabBarFlags_DrawSelectedOverline option to draw an horizontal
-  line over selected tabs to increase visibility. This is used by docking.
-  Added corresponding ImGuiCol_TabSelectedOverline and ImGuiCol_TabDimmedSelectedOverline colors.
-- Tables: added TableGetHoveredColumn() to public API, as an alternative to testing for
-  'TableGetColumnFlags(column) & ImGuiTableColumnFlags_IsHovered' on each column. (#3740)
-- Disabled, Inputs: fixed using Shortcut() or SetNextItemShortcut() within a disabled block
-  bypassing the disabled state. (#7726)
-- Disabled: Reworked 1.90.8 behavior of Begin() not inheriting current BeginDisabled() state,
-  to make it that only tooltip windows are temporarily clearing it. (#211, #7640)
-- Drags: added ImGuiSliderFlags_WrapAround flag for DragInt(), DragFloat() etc. (#7749)
-- Drag and Drop: BeginDragDropSource() with ImGuiDragDropFlags_SourceExtern sets
-  active id so a multi-frame extern source doesn't interfere with hovered widgets. (#143)
-- Drag and Drop: BeginDragDropSource() with ImGuiDragDropFlags_SourceExtern does not assume
-  a mouse button being pressed. Facilitate implementing cross-context drag and drop. (#143)
-- Drag and Drop: Added ImGuiDragDropFlags_PayloadNoCrossContext/_PayloadNoCrossProcess flags
-  as metadata to specify that a payload may not be copied outside the context/process by
-  some logic aiming to copy payloads around.
-- Drag and Drop: Fixes an issue when elapsing payload would be based on last payload
-  frame instead of last drag source frame, which makes a difference if not resubmitting
-  payload every frame. (#143)
-- Debug Tools: Metrics/Debugger: Browsing a Storage perform hover lookup on identifier.
-- Viewports: Backported 'void* ImGuiViewport::PlatformHandle' from docking branch for
-  use by backends.
-- imgui_freetype: Fixed divide by zero while handling FT_PIXEL_MODE_BGRA glyphs. (#7267, #3369)
-- Backends: OpenGL2, OpenGL3: ImGui_ImplOpenGL3_NewFrame() recreates font texture if it
-  has been destroyed by ImGui_ImplOpenGL3_DestroyFontsTexture(). (#7748) [@mlauss2]
-- Backends: SDL3: Update for API removal of keysym field in SDL_KeyboardEvent. (#7728)
-- Backends: SDL3: Update for SDL_StartTextInput()/SDL_StopTextInput() API changes. (#7735)
-- Backends: SDL3: Update for SDL_SetTextInputRect() API rename. (#7760, #7754) [@maxortner01]
-- Backends: SDLRenderer3: Update for SDL_RenderGeometryRaw() API changes. (SDL#9009).
-- Backends: Vulkan: Remove Volk/ from volk.h #include directives. (#7722, #6582, #4854)
-  [@martin-ejdestig]
-- Examples: SDL3: Remove use of SDL_HINT_IME_NATIVE_UI since new SDL_HINT_IME_IMPLEMENTED_UI
-  values has a more suitable default for our case case.
-- Examples: GLFW+Vulkan, SDL+Vulkan: handle swap chain resize even without Vulkan
-  returning VK_SUBOPTIMAL_KHR, which doesn't seem to happen on Wayland. (#7671)

@@ -390,27 +388,27 @@ Long explanation:
 - Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. At the end of the frame, those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code to render them is generally fairly short (a few dozen lines). In the examples/ folder, we provide functions for popular graphics APIs (OpenGL, DirectX, etc.).
 - Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API.
  We carry the information to identify a "texture" in the ImTextureID type.
-ImTextureID default to ImU64 aka 8 bytes worth of data: just enough to store one pointer or integer of your choice.
+ImTextureID is nothing more than a void*, aka 4/8 bytes worth of data: just enough to store one pointer or integer of your choice.
 Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely passes ImTextureID values until they reach your rendering function.
 - In the [examples/](https://github.com/ocornut/imgui/tree/master/examples) backends, for each graphics API we decided on a type that is likely to be a good representation for specifying an image from the end-user perspective. This is what the _examples_ rendering functions are using:
 ```cpp
 OpenGL:
-- ImTextureID should contains 'GLuint' (GL texture identifier).
+- ImTextureID = GLuint
 - See ImGui_ImplOpenGL3_RenderDrawData() function in imgui_impl_opengl3.cpp
 ```
 ```cpp
 DirectX9:
-- ImTextureID should contain a 'LPDIRECT3DTEXTURE9' (pointer).
+- ImTextureID = LPDIRECT3DTEXTURE9
 - See ImGui_ImplDX9_RenderDrawData() function in imgui_impl_dx9.cpp
 ```
 ```cpp
 DirectX11:
-- ImTextureID should contain a 'ID3D11ShaderResourceView*' (pointer)
+- ImTextureID = ID3D11ShaderResourceView*
 - See ImGui_ImplDX11_RenderDrawData() function in imgui_impl_dx11.cpp

 ```cpp
 DirectX12:
-- ImTextureID should contain a 'D3D12_GPU_DESCRIPTOR_HANDLE' (always 64-bits)
+- ImTextureID = D3D12_GPU_DESCRIPTOR_HANDLE

  - nav: patterns to make it possible for arrows key to update selection (see JustMovedTo in range_select branch)
  - nav: restore/find nearest NavId when current one disappear (e.g. pressed a button that disappear, or perhaps auto restoring when current button change name)
  - nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
- - nav: holding space to repeat a button doesn't show button activated during hold.
  - nav: NavFlattened: init requests don't work properly on flattened siblings.
  - nav: NavFlattened: pageup/pagedown/home/end don't work properly on flattened siblings.
