This is a work-in-progress to create a consistent API and finally separate the whole Aseprite base/gfx/ui libs into a reusable C++ library. Classes: app::IFileItem, app::AppMenuItem, app::skin::SkinPart, gfx::Rect, gfx::Border, she::FileDialog, ui::IButtonIcon, ui::Graphics, ui::Overlay, ui::Widget, ui::ScrollableViewDelegate, and UI events
