Hello, Mr. Gong!

First of all, your results look rather impressive to me.

Please note however that it's only possible to "include" a filter into
the next release of GIMP if the filter is implemented as a GEGL
operation.

See http://wiki.gimp.org/wiki/Hacking:Porting_filters_to_GEGL and
http://gegl.org/ fore reference.

If you don't have either time or interest, I do hope that someone will
get involved and make a GEGL port of your filters. I'm sure that will
benefit a lot of users.

Cheers!

Alex
