Shrimp Shader Generator FLTK2 GUI (SVN)

Updated the Oren-Nayar block, and the illumination model headers, to add the option to use the full Oren-Nayar model with inter-reflections (3 coefficients), besides the qualitative model (2 coefficients) - model is chosen via apropriate variable in the block.

Fixed light projector space, fixed UV text in UV block.

Shading rate and pixel samples couldn't be stored as float values in the preferences dialog

Added car paint network example. Added Wolff diffuse model for smooth dielectric surfaces (block+header), and updated Minnaert block information/usage text.

Addded cast for a buggy version of GCC

The coordinate transformation functions were moved to their own header, but extrapatterns.h wasn't including it.

Changed the Blinn specular term name to Phong-Blinn, to avoid confusions, since this isn't neither the Torrance-Sparrow model with Trowbridge-Reitz distribution (C3) nor the Blinn model for dusty/cloudy surfaces, but the Phong model, using the half-vector, instead of the reflection vector.

Fixed undefined references to the AOVs, in non-surface shaders.
