Just a quick update to show I've just started getting the GUI working for texture tools. The node editor is still a work in progress but it seems to do the job.

I still haven't done any significant work on the methods yet but that is the fun stuff .. I've been getting the boring interface and framework working first. There are just some simple test methods as yet, I will be adding more complex blending etc tech soon. It is now pretty easy to add new methods (like plugins) without worrying about the rest of the program.
