But that's it.
Do you render text one character at a time or full line? You could special case each orientation (no on-the-fly transformations) in each widget and pre-rotate textures.

I think the rotation buffer would be faster and have cleaner code than individual widget transformation, unless you special case them. In normal orientation the buffer isn't rotated and would be faster than widget code that can do transformations, even if special cased, right?
