Which I find confusing - I stumbled acroos this yesterday. It is
non-intuitive that something without a toolbox icon has Tool Options.

I mean: Why create proxies and stuff? Just create an appropiate
GimpImage and let the plugin poke on that. I'm not very familar with the
GIMP internals, but I guess we don't need to re-invent the wheel there.
Using a downscaled version of the actual image allows the plugin to
perform _any_ operation it can do on the original image. If there was a
layer-removal plugin, the removal of a layer could be previewed.
