Fixing Move rectangles implementation

Browse Source 
As documented in MSDN, "DxgkDdiPresentDisplayOnly" should copy
each "move rectangle" from a given source point in the source buffer
to the destination. The current implementation doesn't take into account
the shift of the given source point at all. This patch fixies the issue.
