// dear imgui: Renderer + Platform Backend for Marmalade + IwGx
// Marmalade code: Copyright (C) 2015 by Giovanni Zito (this file is part of Dear ImGui)

// Implemented features:
//  [X] Renderer: User texture binding. Use 'CIwTexture*' as ImTextureID. Read the FAQ about ImTextureID!

// 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.
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
// Read online: https://github.com/ocornut/imgui/tree/master/docs
