Shrimp Shader Generator FLTK2 GUI (SVN)

Fixed an wouwou in complex division (trying to store a vector in a float via cx_set), and order of functions (workaround for Aqsis, thanks Tobias Sauerwein).

Updated the shading models header for a fix in the geometric attenuation function of the Cook-Torrance model - the workaround for the Pixie spline() linear basis is no longer needed.

Updated blocks and examples to reflect the changes in the headers to the shrimp prefix.

To avoid potential problems with identically named headers, renamed them with a shrimp prefix.

Basic K-3D .slmeta files generated on scene export

Removed the workaround for Pixie and the He-Torrance geometric attenuation function, since the spline() shadeop is now fixed (thanks Okan Arikan).

Fixed the example scenes, since some blocks had been updated, and the example scenes didn't reflected this.

Updated the wood example scene, since it had retained the old transform block syntax, and there was a problem with the preprocessor directives when deciding when to use vtransform, ntransform, or transform.

Fixed declaration of loop counter in Granier-Heidrich model.

Fixed Granier-Heidrich BRDF, there was an lightsource() left out of the illuminance() construct. Rewrote the accumulators and the respective AOVs.
