Just to give you something to chew over, Mark. Here are
my results with IDL 5.5 on Windows 2000, with a 32MB
NVIDIA GeForce 2GTS graphics card. Screen resolution
is 1280 by 1024 at 32 bits True-Color.

Windows RENDERER=0 0.71 s
Windows RENDERER=1 1.34 s

That graphics card was a couple of hundred bucks, as
I recall. :-)

Cheers,

David
