2.34.1

I would like a bit of clarification here, as I do not see how the use of 
(x^y) is undocumented ("texture grouping"); the documentation for the 
[combine modifier also does not state that () can not be used in the 
texture string(s) to combine.

That said, the changes do make the texture strings look cleaner.

Regardless of the texture strings, I have to admit that the code was put 
together in a relatively short amount of time, so I (or someone else) 
would need to rework the code anyway.
