Hello,

I don't know of any special compatibility issues between Windows and
MacOS X using PLT Scheme graphics. However, MacOS X has a very
different graphics subsystem than many other operating systems and
uses a form of display PostScript for most drawing operations. I have
seen cross platform GUI toolkits (notably for example SWT) break down
on MacOS X if excessive pixelwise drawing was performed on a display
graphics context, since this apparently caused the allocation of huge
amounts of geometry objects.

cu,
Thomas
