Use scissor registers to clip blit operations. This is required

The visible destination rectangle (vis_dst) is the intersection of the
scissor rectangle and the destination rectangle (dst).
The src also needs to be offset if clipped on the top and/or
left sides to ensure that src data is read correctly and appears
clipped when drawn rather than shifted.
