But out of interest if you say wanted to rotate a texture 45 or 30 degrees or whatever, I imagine that requires adding texture math nodes of some sort. Which one would you use and where would it go?

I found this in my material room tips 'n' trix folder, credited to AntoniaTiger:

This example is shown using the Tile node, but it can equally well be applied to the U and V offset inputs of an image node. The angle is set by Value_1 of the Math_Functions_4 node (45 degrees here). Note that your image would need to be tiling for most uses.
