Review request for marble.


Summary
-------

In low-quality mode, the overview map will have a simplified but faster background. First of all, border is skipped. Also, only opaque solid color is considered, which will skip the expensive alpha-blending (SourceOver composition) altogether. In addition, fillRect is way faster than drawPath.

Question: shall we generalize this to FrameGraphicsItem/AbstractFloatItem so that all the layers can contribute to the animation rendering speed-up?
