...a tool that can stretch a selection or layer in a curvy sort of
way (based on cubic bezier patches) on the main window, because I
frequently want to place images inside of other images in such a way
that the scale/rotate/perspective tools are not sufficient....
Probably too late, but could I convince the developers to add this as
an idea for the Summer of Code? Is there any one out there willing to
mentor (or otherwise work on) development of such a thing? Perhaps
combined with making "mesh gradients" from the same sort of patches?
A special case of this sort of stretch tool would cover the recent
Bug 338888 – enhancement request for perspective transform tool:
Unfortunately I am not a student. If there is no student or anyone else
out there interested in working out such features, I will certainly
keep walking down the long road of mapping out the Gimp source until I
understand enough to make my stretch tool (and perhaps add a "preview
opacity" transform tool option, regarding bug #167926).

What I do see on the tutorial page is a potentially very nice
spline-based gradient tool, as Adobe Illustrator has. ;)
Hmm, I hadn't known about that! Illustrator's tool would seem to
correspond to what I had labeled "edit borders only" . The full cubic
patch has more twisting potential. I was inspired from reading about
the postscript shading dictionaries and certain things from Blender.
