The forbidden topic: Glamo OpenGL

After really digging the archives I came across one thread  that has a
lot of good information on the limits of the Glamo and what has been tried
already to get more usefulness out of it. I think it would be good to have
some of the information from that thread on the wiki. Any suggestions on a
good page for it?
It seems for now, trying to work around the scrolling and clipping graphics
as Lally mentioned might be the best course of action. A limited driver
supporting OpenGL ES 1.1 at 320x240 resolution would still be nice, but that
won't solve any of issues with the user interface.
