Currently i'm pretty much into web gl sahder writing.. at least i try. But still there are some things a bit unclear to me. For example which version of glsl es are we dealing with, my guess is 1.0 because you pointed to page 3 and 4 of the reference card.
That brings me to the question if there is any chance to raise this in the near future, because in 1.0 one has to struggle with a lot of limitations (e.g. array initializing, loops etc.).
Another suggestion would be to elaborate a bit more on the pre-defined parameters we can use in shaders. Right now the template.fx speaks of seconds, pixelWidth, pixelHeight etc.. Is that everything? In the file "glwrap.js" there is one additional parameter "LayerScale". Might this be useful to include it into the template?
How difficult would it be to implement furthers params we can use? As i already suggested it would be awesome to pass vector values (vec2, vec3, vec4) on the fly.
