// ImGui BFFX binding
// 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(),
