/* ImGui GLFW binding with OpenGL3 + shaders
 * In this binding, ImTextureID is used to store an OpenGL 'GLuint' texture identifier. Read the FAQ about ImTextureID in imgui.cpp.
 *
 * You can copy and use unmodified imgui_impl_* files in your project. See main.cpp for an example of using this.
 * If you use this binding you'll need to call 4 functions: ImGui_ImplXXXX_Init(), ImGui_ImplXXXX_NewFrame(), ImGui::Render() and ImGui_ImplXXXX_Shutdown().
 * If you are new to ImGui, see examples/README.txt and documentation at the top of imgui.cpp.
 * https://github.com/ocornut/imgui
