Linux machines that use the X Window manager have something called xdotool that can record window inputs and replay them. I use this to do the following in Gimp
1. Alpha to select Original Image
2. Make a new layer
3. Name it Effect
4. Move it behind the original
5. Press B for Brush tool
then I press a custom key binding to stroke from selection. You need to set this manually.
Video Footage of it here. I am manually hitting a key to stroke.
