True. But currently I have the "main" function I would like to
parallel something like this:

drawPixel x y = do openGLDrawPixel x y color where color = calcColor x y

But it is probably really better if I first calculate everything and
then just draw it. It is easier to parallelize (will have only pure
functions) and also I will not have those OpenGL errors.

Thanks everybody
