Any chance of seeing a more compute like version of "CrestFillMaskArtefacts"?

Please describe the desired feature/behaviour.
CrestFillMaskArtefacts right now uses a lot of load texture instructions.

Supporting images/mockups, or example reference videos are very helpful to communicate ideas.
using a more compute like approach utilizing group shared memory should reduce the number of load texture instructions significantly.

Tried it and performance was worse when measured using Nsight. But maybe I was doing something wrong. You can see it for yourself here: perf/fill-mask-shared-memory.
