GLSL: WTF is a gsampler?

category: general [glöplog]
 
I've found some glsl functions that take gbuffers but I can't find anything about them on the specification. Google also doesn't return anything.
What are those things?

In the prototypes below, the “g” in the return type “gvec4” is used as a placeholder for nothing, “i”, or “u”
making a return type of vec4, ivec4, or uvec4.

Mystery solved. They could have chosen a better letter for that.

A gBuffer stores gStrings.

Those texelFetch functions, are they faster (more cache friendly, skip a few steps) than texture2D?
