[racket] parallelism

By using "for/parallel", I would be promising the compiler that

This sounds like what an OpenGL (fragment) shader effectively does.
Can I plug my RacketGL package on Planet?
With this you can access GL shading language functionality from Racket.

The shader itself though has to be written in GLSL.
No (subset of) Racket -> GLSL compiler. Yet.
