- Demo: Fixed Overlay: Added a context menu item to enable freely moving the window.
- Examples: Allegro 5: Added support for 32-bit indices setup via defining ImDrawIdx, to avoid an unnecessary conversion (Allegro 5 doesn't support 16-bit indices).
- Examples: Allegro 5: Renamed bindings from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
- Various minor fixes, tweaks, refactoring, comments.
