ofn-luminosity-masks

[Ofnuts]

My own take on luminosity masks. While it pays its dues to PatDavid's canonical tutorial on the subject, it creates the same masks using a different and (hopefully) more efficient method that allows:

• to create a luminosity selection from the current layer in one single click (or one keystroke if you defined shortcuts)
  
• in a future version, to define your own masks
  

As usual the script can be found here.  Restrictions in this version:

* Only PatDavid's masks, no custom masks yet
* Only for Gimp 2.10 (seems to hit a bug in 2.8)

Enjoy.
