This can already be done with a colour map layer:

Rotate the texture in the colour map layer and make the text (or any other layer!) point to this colour map layer.
When the texture isn't animated, a low-tech solution is to rotate the texture in a paint app.

A colour map layer can be used as a displacement map, so the same trick can be used here.
