// [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// FIXME: The transition from removing a viewport and moving the window in an existing hosted viewport tends to flicker.
// [X] Renderer: Support for large meshes (64k+ vertices) with 16-bit indices.
// Missing features, issues:
// [ ] 64-bit only for now! (Because sizeof(ImTextureId) == sizeof(void*)). See github.com/ocornut/imgui/pull/301
// Important: to compile on 32-bit systems, this back-end requires code to be compiled with '#define ImTextureID ImU64'.
// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
// This define is done in the example .vcxproj file and need to be replicated in your app (by e.g. editing imconfig.h)
// You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
// If you are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2020-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
// 2019-05-29: DirectX12: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
// 2019-04-30: DirectX12: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
