I took at graphics context proxy and asked it for its plane mask.

At first I thought that maybe the type was being declared as signed integer,
thus the overflow, but this makes no sense. It is defined as unsigned long,
and the primitiveMaker (the one distributed with the X stuff. CVS seems
to have botched its revision tag...) generated a macro that has that.
Could the macro be wrong? I have yet to delve very deep into the macros
that are used. Two or three levels of nesting, and I give up :-)
Thanks.
