D3D9: Offset vertices used to copy textures by 0.5.

Browse source 
I __think__ this is the actually correct way to do it, but not sure. Someone please have a look at this...
Not sure if this changes anything anyway, since we're using scissor rects to clip this stuff anyway... Maybe the screen edges weren't cleaned properly before though.
