What's the best way to do (exact) 90-degree rotations in PyGame? There doesn't seem to be a separate "transpose" operation in the "transform" module (I.e. an operation that swaps x & y coordinates).
Does the "rotate" function special-case 90-degree interval rotations? Or is it more efficient to convert a PyGame Surface to a Python Imaging Library image and then transpose that? (PIL does have a separate "transpose" method). How efficient can this be? If I need to get a mirror image or a transposition of an existing surface (say a full-screen 1024x768 image), is it worth caching the result to disk? Or would it be faster to just flip it in memory whenever I need it? (IOW, how does a 90-degree rotation or a "flip" compare to a disk I/O on most computers?) BTW, I tried to look this up, but I can't find a discussion of it in the documentation, and wasn't sure how to look it up in the ML archives.
