[GRASS-dev] map display enhancement

[Vincent Bain]

Hi list !

playing around with multiple layers in the map display I wonder if
anyone ever suggested to introduce blending modes beside the already
implemented "opacity" option. I mean it would be great to be able to
combine layers with various options (commonly known as Multiply, Screen,
Addition, etc.).

It's probably a big task. Let me know if you think it is worth opening a
ticket for that.

Yours,
Vincent.
