Shrimp Shader Generator FLTK2 GUI (SVN)

UI editable storage for outputs

Added storage support for block outputs

Fixed typos, and removed storage="uniform" from output types (we need to fix this, this should be accepted).

Updated bake3d() block for missing channel entry. Fixed typos in bake and texture3d. Added output type dependency in some mathematical functions.

Added bake, bake3d, texture3d, shadername shadeops. Updated some global variables storage, moved photonmap to raytracing section.

Updated storage for string type pads, updated texture block, and environment for Pixie.

Updated indirectdiffuse() and occlusion().

Updated compatibility for trace and occlusion shadeops in the different implementations.

Fixed hyperbolic tangent block, updated trace and transmission blocks to be able to deal with different renderer implementations.

Shader code constants automatically defined with integer values for the shader preprocessors
