I found that I misread the manual page on wrastop (Stupid me!).  I assumed
that since the address was a short that the width was the number of shorts.
NO. The width is the number of bytes. (It also seems that the number of bytes
must match the number of shorts*2). (Even if the actual width is only 7 pixels
(for example)).
