This has nothing to do with a Warp tool, really (because a Warp
tool doesn't use a brush), but the answer is yes, it is very
I would be interested in getting opinions on some of the open
questions about how such a tool should work. Here are some
of the questions:
1) How should a filter-brush handle the settings for the filter?
Should it run the filter's dialog when activated in order to get
settings, or have a button to run the dialog, or use the
default settings, or the last settings used, or what?
2) Should a filter brush, in effect, apply the filter to the drawable,
and then clone from the result at each stroke? Or should it
reapply the filter after each brush stroke? Or after each brush
mark? Or should this be an option?
In any case, applying a filter with a brush is basically a fancy
kind of cloning, so there is nothing intrinsically all that difficult
about it. There would probably need to be a bit of new machinery,
such as a mechanism for distinguishing "paintable" filters, and a
way to run a plug-in in "dry-run" mode -- so that it sets up
parameters but does not actually alter the image -- but
nothing incredibly challenging.
