Support transparent windows. Bug: output may expect pre-multiplied alpha; we do not output that. Not trivial to handle since WGPU enumerates several modes but not all are supported, so possibly we should support both pre- and non-pre-multiplied alpha output?
Support multiple window decoration modes: none, frame-only, frame+titlebar (toolkit drawn), server-side. Limitation: winit does not currently support server-side decorations on Wayland.
New (very basic) graphics for toolkit-drawn titlebar (currently lacking support for an icon). Need to decide what image formats we support for this; use
Imagewidget or justVec<u8>like Winit. Limitation: theTitleBarwidget is defined in KAS-core thus cannot use KAS-widgets's widgets. At least, this is the current state.Adjust

wayland,x11. Do not usewinit/wayland-csd-adwaitathus reducing dependencies. Size ofgallery(release, stripped): previously 18M, now 17M, down as low as 11M (minimal features only on X11, which still includes WGPU and resvg).
