// Implemented features:
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
// [X] Renderer: Multi-viewport support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_ViewportsEnable'.
// [x] Renderer: Desktop GL only: Support for large meshes (64k+ vertices) with 16-bits indices.
// 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)
// 2018-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2019-XX-XX: Platform: Added support for multiple windows via the ImGuiPlatformIO interface.
// 2019-05-29: OpenGL: Desktop GL only: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_HasVtxOffset flag.
// 2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
// 2019-03-29: OpenGL: Not calling glBindBuffer more than necessary in the render loop.
// 2019-03-15: OpenGL: Added a dummy GL call + comments in ImGui_ImplOpenGL3_Init() to detect uninitialized GL function loaders early.
