Hi, I just wanted to send a note saying that I committed an additional method to the Transforms class that transforms angles. The basic idea is to transform an angle at a point to a new angle at the corresponding point in the transformed coordinate system. The included method is generic and should work well for almost any transform provided that the spatial scale isn't too small or too large. Much faster algorithms that would work regardless of spatial scale can be found for particular transforms, particularly affine transforms, but I haven't added these yet.
I also added an example script that shows how to use this method to plot text rotated so that it aligns with a line in a figure ( text_rotation_relative_to_line.py ). I initially intended to use this method to give text objects the option to be rotated with respect to the plot coordinate system (as opposed to the screen coordinate system), but I haven't gotten around to finishing this yet.
