Node for calculating the "medial axis transform and "straight skeleton"

Vector straight skeletons can be used as efficient rigs for animating more complex 2D shapes. Skeleton rig will automatically have the most efficient amount of control points per shape.

In raster graphics MAT in a form of gradients are a great way of making various masks that are either very time consuming or impractical to do by hand. MAT-based masks are also very useful in making textures for 3D. An example of how this could work is Distance Map in GIMP: Filters -> Generic -> Distance Map
