Basically a similar idea to Parakeet or Numba, but with GLSL as a target. The problem with doing this on WebGL (which is essentially GLES2) is that the internal precision of the pipeline is not required to be a full 32 bit float. There are 10 bit integers and 20 bit floating point numbers and all sorts of funny number formats in the hardware. When most scientific/numeric computation is done in 64 bit double precision, going to less than 32 bits is a problem. Of course it still could be done in WebGL, the problem is that running it on different hardware would yield different results. If this is acceptable (e.g. image processing where bit-accurate results are not required), then why not.
