random_surface

declaration:

    function random_surface(width, height) => vid or BADID

Generates a pseudo-random (poor) image in the interval (20-255) with the same value in all colour-channels. Will only ever return BADID when out of memory or VIDs in the current context.

** future changes / deprecation: **

Mostly used as a quick hack and should ideally be replaced with a proper and quick noise- function where you can specify the frequency and number of octaves wanted. Then it can be used for lots of tasty 3d tricks.
