Subject: Fix for Bug [770364] MI2: Amiga - Segfault when entering bar Possible
 fix for Bug [770085] MI2: Amiga version always crashes after a few minutes

Corrected OOB graphics writes in proc3_ami() by fixing the
mask to properly detect negative Y values. Don't know if
this is the right way to fix this -- there are enough GFX
bugs in the Amiga code as to make assessment difficult --
but at least it averts crashes.
