	You have got to define what "Higher Priority" means.  I think this
is why we have had so much trouble trying to answer your question.   I think
we've got the graphics situation straight... your blitting a 4plane image
onto a 4plane screen.  So, on a pixel by pixel basis, what constitutes
'higher' priority??
