-// dear imgui: Renderer Backend for modern OpenGL with shaders / programmatic pipeline
-// - Desktop GL: 2.x 3.x 4.x
-// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
-// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
-
-// Implemented features:
-// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
-// [x] Renderer: Large meshes support (64k+ vertices) with 16-bit indices (Desktop OpenGL only).
-
-// About WebGL/ES:
-// - You need to '#define IMGUI_IMPL_OPENGL_ES2' or '#define IMGUI_IMPL_OPENGL_ES3' to use WebGL or OpenGL ES.
-// - This is done automatically on iOS, Android and Emscripten targets.
-// - For other targets, the define needs to be visible from the imgui_impl_opengl3.cpp compilation unit. If unsure, define globally or in imconfig.h.
-
-// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
-// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
-// Learn about Dear ImGui:
-// - FAQ https://dearimgui.com/faq
-// - Getting Started https://dearimgui.com/getting-started
-// - Documentation https://dearimgui.com/docs (same as your local docs/ folder).
-// - Introduction, links and more at the top of imgui.cpp
-
-// About GLSL version:
-// The 'glsl_version' initialization parameter should be nullptr (default) or a "#version XXX" string.
-// On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"
-// Only override if your GL version doesn't handle this GLSL version. See GLSL version table at the top of imgui_impl_opengl3.cpp.
