kostya is IIRC correctly going to rewrite the table generator this weekend
other things to do

split asm code out cleanly, maybe similar to dsputil maybe not
(its important that its clean, has a cleanly documented API betwen th
C/ASM on one side and the code calling it on the other, and of course
it must be fast)

split/put under #ifdef the optional GPL optimizations so swscale can be
compiled in a pure LGPL mode. (this is the only thing AFIAK except the table
generator that is needed for droping the old scaler)

see the related past gsoc project there where many other ideas of what
could be done

There will always be a question for which you do not know the correct awnser.
