FIXED: unaligned access on DEC UNIX compile

[Tom Kacvinsky]

Well, the problem wasn't in the grayscale renderer.  It was in
grx11.c.

Here is a patch.  The unaligned access occured because ulongs on axps
are 8 bytes wide, but there was a cast to ulong* on a pointer that was
accessing memory on a 4 byte boundary.
