Warning

I tested all the lo-res routines except scan, and they
seemed to work, but the hires plot routines
seem to use some section of memory that Hyper C 
requires.  I seem to remember something about 
the hplot and draw routines using space in page 3
to calculate vectors, but I'm not sure.

Does anyone know what areas of memory the hplot/hplotto/draw/
xdraw routines use?

I could just copy the areas before making 
graphics calls, and then restore them.
