fix [3008290] passion GB surface does not send surfaceChanged notification after size change.

The video has the same aspect ratio than the window, so the window size doesn't change.
In turn, onSizeChanged() is not called, which is where surfaceChanged() is eventually called from.

we now override setFrame() and always call updateWindow from there instead of from onSizeChanged()
