Hi !

To use custom shaders you will need gcc on Linux and lcc on Windows,
I decided to go for lcc because it is much easier to install then gcc
(mingw32/cygnus), but if any one wants to use gcc on Win32 this will
also be supported of course.

The custom shaders is just a C function in a dll/shared library, so
it's a bit like plugins, procedural textures, displacement and light
shaders will be supported to start with, I have plans to add custom
primitive objects also.
