Hi,
I have made several improvements to bmovl2 since my last post, so I
thought I would share the most recent update. Here is a list of
changes:
* Image identifiers are arbitrary strings instead of integers.
* Images stored using linked list; there is no longer any limit to
the number of images.
* Blending process now more precise (thanks to Billy Biggs for his
advice).
* MMX optimizations.
* Some decent optimizations for non-MMX.
I've written a test program as well (it requires imlib2), which you can
fetch here:

Performance is the most significant update. On my Athlon 1400, CPU
utilization of mplayer dropped from 80% to 45% for my test case.
I'm happy to hear about your comments or suggestions.
Cheers,
Jason.
