WPE uses its own drawing area implementation, which is actually a fork of AcceleratedDrawingArea, but simplified for the case of compositing being always forced. AcceleratedDrawingArea already handles the case of compositing being forced, so now that WPE is upstream we could simply use AcceleratedDrawingArea instead.
