Consider Texture paint area G'MIC effects panel

[myselfhimself]

• Idea: add G'MIC filters for any paintable canvas

• Possibly shorter time to market than compositing nodes.. Unsure yet.

• Backend: gmic-py: load canvas buffer, modify it using a G'MIC / Python Blender UI panel, push it back to canvas

• Inpsiration:
