// ImGui Renderer + Platform Binding for: Allegro 5
// (Info: Allegro 5 is a cross-platform general purpose library for handling windows, inputs, graphics, etc.)

// Implemented features:
//  [X] User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
// Missing features:
//  [ ] Clipboard support via al_set_clipboard_text/al_clipboard_has_text.

// 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.
