I think this fixes bug #1291074, which is a masking glitch in Amiga v5
games. The mask pointer and maskbit weren't properly updated for the first
pixel of each new row.
Note that I do not have any of the Amiga games myself, so this fix is
based on observing what happens when forcing the PC version of MI2 to use
proc3_ami() instead of proc3().
