I have been seeking answers to the following related questions, but cannot

(1) What is the GLSL support version? I ask because I'd like to explore use

of the Uniform Buffer Object, which is supported in OpenGL 3.1/GLSL 1.4,

and perhaps the Geometry Shader of GLSL 1.5. UBOs, FBOs would be potentially

useful in captured delayed textures and gathering statistics on texture

(2) Are read/write buffers of the UBO and FBO sort surfaced in jit.gl.pix ? I've

seen some references to FBO but only in terms of errors encountered. My question

is more related to whether one can read/write to this secondary memory area. As

long as this sort of buffer is supported in shader development (e.g. .jxs) then

this would be useful even if not surfaced to the language in jit.gl.pix. In reviewing

the jit.pix and jit.gl.pix documentation, I couldn't see anything like that.
