Correctly handle using GL pixmaps that still have an active engine.
In the case where a GL pixmap is used when there it still has an active
engine we need to ensure that the pixmap has been flushed from the
render FBO first. The newly added QGLPixmapData::copyBackFromRenderFbo()
handles this.
In addition, because several GL 2 paint engines can be active on the same
context at the same time, we can't make any assumptions and need to call
the newly added QGL2PaintEngineEx::ensureCreated() in the beginning of
any state-dependent paint engine function.
QGL2PaintEngineEx::ensureCreated() correctly transfers control to the
current engine if a different engine is active.
Running lance with -pixmap and -graphicssystem opengl works correctly
with the GL pixmap backend now.
