Fix some rendering/scrolling artifacts with QX11GLWindowSurface
The GL2 paint engine sometimes adds a 0.49,0.49 offset when
rendering into a multi-sampled QGLPaintDevice. The problem was that
we weren't updating the QGLContext's QGLFormat with the EGLConfig
so the paint engine thought it was rendering into an surface without
multisampling and thus added the offset.
