Is there some completely different and maybe better way of rendering
the image? Because I noticed that in fact I do not really have any use
for OpenGL (I draw pixels on a 2D plane). So maybe is there some other
portable way of rendering a 2D image, which would be easier to
parallelize? Maybe of precomputing the image in completely functional
way and then only draw the whole image at once to the screen buffer
(now I call OpenGL draw pixel function for every pixel I want to draw
- this is probably not the best way).
