The problem is that a render target surface is created,  CreateSurface 
always computes the size using power of 2 width and height.
But in GetDC the original size is used in the case of the render target. 
This mismatch is the source of the problem.
I guess we should compute the size in CreateSurface using the original 
size in the case of the render target.
If this is the right fix, I will send a patch.
