# Procedural textures

## the idea
We need a way to produce textures procedurally.
These texture can be generated on the CPU or the
GPU with a shader and the proper rendering target,
and then sent back to main memory.

## What textures?

The procedure can be use to pre-calc env maps
and lighting maps, or textures (fractals, fonts, etc.)

## how

This could be integrated in the asset system as
a special "compression" case (instead of "NONE", you
have "PROC(the_function_name_to_call)" as compression
type).

## code

let's have a proper 'src/procedural' sub-directory
with all the code related to procedural textures.
