This may have been lost in the longer thread above, but what
interpolation are you using? You may see a good performance boost by
using interpolation='nearest'. Also, with your clip changes and with
Eric's changes is it still painfully slow for you -- how much have
these changes helped? Of time time spent in make image, how much is
_image.fromarray, ScalarMappable.to_rgba and _image.resize?
