I am having some problems using the libgrx2.0 library.  I need to do some
double-buffering and the only way I can see of doing this under grx is
using contexts.  I want to write to a memory (offscreen) context, copy the
context to the screen context and then clear that context ready for the
next screen load.  I have a routine which does this using straight C by
writing to the video address and a manual buffer but I wanna use the
drawing functions of libgrx to make my life one whole lot easier.
If anyone out there has any idea on how to do this, or better yet some
pre-written code then please e-mail me.

Cheers.
