It's GLSL 110 then, which sadly not very decent :( But i assume those who will works on shaders can migrate from todays shaders to v110, just need a bit of rewrite..

Probabaly there were reassons to go for v110 firstly and made it all as extensions ?

What intersting me most, how complete GLSL support even of 110 are, and were there written GLSL parser/converter from scratch or something else were used ?
