This has been on the roadmap for a while.

This is NOT doable as a plugin. This needs to be tone in the core, In
the part thats responsible for drawing the image projection.

C will come as a bit of a shock then ;) no garbage collection etc. but
If you want to the skills can be aquired.

thats the business of the projection alright.

Let me warn you, its a lot more work than you think, more o if you
have never used C or GIT. On the other hand its easier to learn than
one would expect for c. The functionality you will need to alter is
AFAIK nicely separated from the rest.

If you still want to do it, please join us in gimp net #gimp irc channel.
