[beagleboard] A primer on on porting openGL based applications to GLES, and performance

Koen has already had Ogre3D running and there is an openembedded package
for it. The package pulls Ogre from an older copy of their development svn
which changes fairly often. I am trying to get the Ogre GLES render system
to compile under Linux again.

Once I finish that I plan to turn my attention to OIS and also CEGUI.

What I would like to know more about is getting Ogre GLES to run without X.
Basically run it from a console-image. That will probably be the last step
that I work on.
