[FFmpeg-devel] [PATCH] Add filter_limit to VP3 loop filter paramaters

The C implementation of the VP3 loop filter uses a table of pre- 
calculated values for the filter function. This doesn't work so well  
in SIMD; it's faster to calculate the function with the limit value.

Implementing the C version without the table is slightly faster on my  
Penryn, but about 20% slower on P4, so it's probably not worth it to  
replace the C version to get rid of the table completely.
