Comment (by llogan):

 Replying to [comment:2 edelsohn]:
 > swscale methods frequently appear high in profiles.  The routines have
 been optimized for x86.  IBM is sponsoring bounties to enable similar SIMD
 optimizations for the POWER architecture.

 It would be helpful if access to such hardware was provided or if a
 machine could be donated. Is this a possibility?
