[jitter] Tannenbaum Jit.mxform2d

Hi,
You're not going to be able to solve this without gaining a more 
thorough knowledge of Jitter, OpenGL, and the various objects and 
techniques used in the original patch.  My advice would be to set this 
project aside for a minute and go read the OpenGL section of the Jitter 
tutorials.

I will give you one hint: jit.mxform2d will never work for what you are 
aiming to do (think jit.gl.*).

Best of luck,
Andrew B.
