Hi, No, it's only destructive if we have no way of regenerating the cache as needed. With GEGL, we can cache just at the newest node in the graph. Stroke information can be fully stored in the node. I'm confused. From my understanding, if stroke information is stored in the node, then the

Hi, They do not need to be made fully non-destructive, for the paint core I have been experimenting with on top of GEGL[1] I have both a destructive and a non destructive version. The difference between them being that the destructive one continuously replaces the contents of a GeglBuffer
