Improved QPainter API for allowing native painting in GL / VG.
Previously we were using QPaintEngine::syncState() which is not ideal naming-wise, since it actually prepares for native painting instead of syncing the painter's state to native state. Reviewed-by: Trond

- - When mixing OpenGL and QPainter calls you need to first call syncState()
- on the paint engine, for example "painter->paintEngine()->syncState()".
- This is to ensure that the engine flushes any pending drawing and sets up
- the GL modelview/projection matrices properly.
+ - When mixing OpenGL and QPainter calls you need to surround your custom
+ OpenGL calls with QPainter::beginNativePainting() and
+ QPainter::endNativePainting().
+ This is to ensure that the paint engine flushes any pending drawing and sets
+ up the GL modelview/projection matrices properly before you can issue custom
+ OpenGL calls, and to let the paint engine synchronize to the painter state
+ before resuming regular QPainter based drawing.
- Graphics View has undergone heavy optimization work, and as a result of
this work, the following behavior changes were introduced.
