Texture function refactoring
To make it easier to branch on the different texture
fetching options, a new TextureFunction class is
introduced here, which performs the string comparisons
and identifies the different options.
I also had to add a 5th argument for textureGradOffset
and textureProjGradOffset.
I added function stubs (with the UNIMPLEMENTED markers)
for all new texture functions.
