Volume textures

[unicomp21]

A way to simulate 3D toroidal volume textures using 2D texture support would be fantastic. ie Use existing bilinear sampling to build trilinear sampling in the shader. Once WebGL2 rolls out, this can be removed.

I will add this to the feature request list. However, this is not a priority, so you may try implementing it yourself if you need it now. Pull requests are welcome.
