QtWidgets: Improve native and top-level OpenGL widget performance
Since 7c6625b105511191f739d07dc658094ff6f682ac native OpenGL widgets
are able to render, but performance is very low. It also slows down
rendering for top-level OpenGL widgets.
Render-to-texture widgets prevent triggering unnecessary backingstore
painting when only the OpenGL content changes.
This patch makes possible to use that feature for native and top-level
widgets by calling "markDirtyOnScreen()" function only when necessary.
This patch also prevents native and top-level OpenGL widgets from
flickering during resizing.
