Ok...let's try this again.  (My usual server is down, and the message
I sent off to some no-name news server seems to have been swallowed up
into the void of the net.)
Here's my question:  How can you (is it possible?) to do high-speed
screen writes using GRX?
The game engine I'm working on needs direct control over every pixel
on the screen.  (640x480 16 bit)  Unfortunately, the fastest I can
get GRX to run (updating the _entire_ screen every frame) is about
0.5 frames per second.
Does anybody know how to do this _without_ assembler or machine-level
SVGA code?  (I'd rather not have to learn those now, but if it's necessary...)  Thanks for any help.
