hmm, possible. I don't remember if it is possible to read from a multi
sample texture without a) using special sample functions in the shader
or b) performing a glBlitFramebuffer (or similar operator) to resolve
the multiple samples.
I'm also pretty sure that you'll not get around touching all
*TreeHandler classes to make them create multi sample textures otherwise
I doubt you'll get multi sample rendering on the intermediate steps.
Cheers,
Carsten
