I made a new GEGL plugin targeting Gimp 2.99.19 non-destructive build. Specifically so users can combine an outline and bevel together in one 'layer effect' instead of putting it on a layer above. This plugin still requires the use of the 'normal' blend option if you don't want it on the layer above. I did this for flexibility so people can blend it with other blend modes if they want.
