Offscreen rendering of the mainframe at the QWebFrame level

This patch render the frame offscreen on a pixmap and always paint the pixmap
in paint event.

The advantage of storing the pixmap at the frame level are:
 - improve the speed of graphics web view && qweb view
 - we can avoid completely GraphicsContext in some cases
 - we can have support for multi-frame

This is preliminary work, not meant to be integrated. It does not yet integrate
the work of Kenneth
