[jitter] Apply shader for entire context

Hello,

I'm trying to apply a transformation (like a keystone) on a render  
which contains several objects (jit.gl.sketch, and rr.gl.ogre), but  
it's not so easy !!!

We write the shader,  but I don't understand how to apply it on the  
render.

Maybe someone hav a clue?
