* Remove DC refcounting (we trust GDK to always do begin_frame/end_frame calls in pairs) * Now that there's no GDK-provided double-buffer up the stack, double-buffering is implemented here (though it's disabled by default - in my tests it didn't provide any visual improvements, but did decrease performance). * For some reason delaying window resizes until the point where we need to blit the double-buffer into the window leads to visual glitches, so doulbe-buffered windows are resized in begin_frame, same as non-double-buffered ones. * New code to clear the paint region, for all drawing modes. Hopefully, it isn't duplicated anywhere up the stack. * GL has its own context now, so remove any GL-related comments. * Layered windows are still used (because cairo actually works better with them) * A bit more code re-use for layered windows * Some functions that were local to gdksurface-win32.c are made usable for the whole backend * Drag-indicator drawing is temporarily commented out to match a similar change in X11 backend
