Usetex now supports arbitrary angles with the Agg backend. It grabs only the greyscale part of the usetex image (which isn't new -- usetex has always thrown away any color coming from (La)TeX), and then uses draw_text_image to do the drawing. (draw_image continues to not support rotation, but that is probably best done elsewhere anyway, if the need ever arises).
