Hello, I am working on a plugin to allow another application I'm working on to run gimp instead of the user. The idea is a 3d painter application that can make use of all the gimp tools but through a 3d view instead of the normal 2d texture. I already have implemented enough to use the pencil remotely.

My question is, is there any alternate way to use the tools other then the gimptools methods? The problem is I want to see updates as the user does things, and to do that I need to be continuously passing information to the plugin, but because the tools count each call to gimp_pencil for example as an undo able operation undo becomes pretty useless. A way to do the operations but not remember it for undo until I say would be a possible solution.

One other thing I noticed is even if I queue all data from the user exactly as inputted I don't get enough input points from gtk to provide smooth lines. I assume gimp is interpolating between the points it gets in order to get the smooth effect, is there a way for the plugin to use this or will I need to do this myself?

Thanks Daniel
