Sorry if you got this the second time Lewis, I thought I replied
to this message this morning, but I don't see my reply here
on the list, so I will do it again.
The only way it will be slower is that if I include a clipper
for my PUT_PIXEL routine to make sure you can't draw off the
screen and then someone else makes his own clipper routine not
being aware that the libray already does it. Then there would
be two clippers going. The speed difference probably wouldn't
be much comparing the two methods.
Anywayz, I've decided not to include it for the PUT_PIXEL
routine and just let the programmer handle it. I just need to
update the Docs to warn about drawing a pixel off the screen which
will most likely freeze up one's computer.
