Hello,

this is my first time writing to this list. I've done some speedup
(about 40%) of the oil paint simulation (-paint option of convert)
through parallelization using OpenMP. As an example, on a 2816 x 2112
pixels image, it goes from

real	0m57.945s
user	0m57.596s
sys	0m0.192s

to

real	0m32.544s
user	0m57.748s
sys	0m0.284s

on a Intel Core 2 Duo 2GHz. I plan to do some timing on a 2x quad core
processor also, to see how it scales.

The patch is attached and can also be downloaded from
