// 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] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID in imgui.cpp.
//  [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
// Issues:
//  [ ] Renderer: The renderer is suboptimal as we need to convert vertices.
//  [ ] Platform: Missing 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 are new to dear imgui, read examples/README.txt and read the documentation at the top of imgui.cpp.
