// 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 copy and use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
