This is the base shader class. (not used directly to develop shaders)
This class have all the support methods that that a template needs.
Also have all the client support methods.

renderer code is define as a method, as in the following example:

        def delight(self, parameters):
                return ('','')

The method must have the name of one of the renderers defined in
the _renderers method.

The method will be called by the clients, which will pass
the "parameters" attribute to it.

The parameters attribute is a dictionary that contains all the
parameters returned by the parameters method, but already evaluated
by the client. This way the method can evaluate the parameters input
from the user to build up the shader parameters and code.

The method should return a tupple, where [0] is the shader
parameters and [1] is the shader code.
