Hi there!

I'm porting a graphics intensive program to the pc, using djgpp at the moment.
I have the 1.03 GRX lib, which works ok. We currently save the current
context, and extract the video base memory in order to write directly to it.
This is sufficiently fast, but obviously we really need to use frame buffering,
ie, write to a context not visible, then switch this to be the displayed
one. How do we do the switching??

Sorry if this is a dumb question, the docs don't seem to cover it.

Thanks,
Steve
