Oh.. of course. Sorry, I was thinking about things like gradient-map,
normalize, and tile. More complex things like warp, gimpressionist, or
sample colorize didn't occur to me..

Okay. The kind of plug-ins I'm talking about are also too lightweight
for the current framework -- it's best if they run quickly -- and my
current workaround can run them quickly (20 times / second for the
average one). Truthfully UI manipulation doesn't fit in that area,
almost everything is either about a quick manipulation on the image
(vector-smooth a binary selection, colorize a greyscale, 'apply' a
layer) or a quick change to the context (interpolate colors, colorize
a brush, sieve a brush). I really think there is a place for this type
of simple 'macro' host. Hopefully I can get it into releasable state
soon. I'll just have to hack around the rest.)
Thanks for your time.
