I wrote a program which does raytraces and displays the picture on the screen
by directly manipulating the bits of the SE's monochrome screen.  Now I would
like to show the pictures on a Mac II.  Even in monochrome screen the bit
manipulations don't work properly, so I moved to quickdraw.  Using the moveto
and lineto functions, screen drawing now takes minutes rather than seconds.
Does anyone out there have info on how to draw in gray tones with quickdraw,
then how to do it directly?  All of my documentation on quickdraw is pre-Mac II

Thanks for the help.
Jim
