[PD] [GEM-dev] gl stack underflow

[Matteo Sisti Sette]

Thank you for pointing me to the examples, but it definitely seems there 
is some kind of interaction with [pix_snap]: even if I force 
[gemframebuffer] to use texunit 0 and my textures to use texunits 1,2,3 
and 4, I still get under/overflows as soon as pix_snap takes a snap, and 
my shader is using a snapped picture (which does not correspond to any 
other texture) instead of the texture I expect it to use.......

Well I will try to post a simplified patch because this explanation of 
mine is a mess, but it seems I have to figure out how to avoid pixsnap 
to mess with textures. It does not accept a texunit message (dunnow if 
it would make any sense)......
