Node for tweening "topo lines" across several guide paths #2316
Description
This is sort of like the Morph node, but it should work despite changes in topology of the curvature and it should take multiple layers (as a GraphicGroup stack, lavender-colored data) and output either one (with a t value) or multiple paths that interpolate it.
In this rough hand-drawn example, the RED paths are the end guide paths, the PINK paths are the intermediate guide paths, and the GRAY lines are the tweened paths. In the real output, none of the guide paths would be directly preserved, only the interpolated versions, ensuring they are evenly spaced with each other given some density or count parameter.
