The internal code of RayShade supports a complete=20
ray tracing renderer, we could have all these=20
features in Quesa passing in some way the=20
necessary parameters, but the most part of these=20
parameters aren't actually present in Quesa.

It makes sense for me to go on with this simple=20
and fast implementation of reflection, because it=20
doesn't request any modification to the=20
applications that  actually support Quesa and all=20
of us can try and experiment this solution.

But there aren't simple solutions like this for=20
other RayShade functions, like procedural=20
shaders, bump mapping and others.

We could implement these parameters in Quesa or=20
pass them to RayShade and other renderers as=20
custom attributes.

I prefer the first solution, because it is more=20
general and the same parameters can be shared by=20
all the renderers. The second solution has the=20
advantage of not requesting any modification of=20
the Quesa code, it could be done modifying=20
Rayshade only, anyway a standardization of the=20
attributes is necessary.
