Hello Friends, 

I've been working on a program to find all intersections between paths in an image. ( Just paths at the moment not shapes, circles etc ) 

It produces a layer which contains mini paths which when combined can be used as a cutting template for things which are below.

I've had good success with Moini's path ops extension, using the 'cut' option. https://gitlab.com/moini_ink/inx-pathops/

At the moment it can't detect T-Junctions :( but hopefully it will in future. 

I plan to release it at some point when further optimisations have taken place.

Sadly it does still require the use of 'flatten' to correct transforms in the original SVG.

Any feedback appreciated.
