The future of selections and masks in Krita

[Thomas Zander]

Hi boud!

First of all; do you agree on the use cases?  Did we miss anything?
We _concluded_ a solution from them, but if another solution satisfies the 
usescases and even other usecases, the ideas can change.
Another theory is just fine, as long as the usecases are satisfied.

Ok, I'll ask the guys to explain that to me tomorrow.

So, you are suggesting that a selection has an effect on the transparancy 
of the layer?
Or how will the user see the difference between a selection and a mask?
I kind of had the impression the idea you and I had were kind of the same, 
but the presentation to the user was slightly different.
Ok, I'll ask the guys to explain the design you referenced above to me 
tomorrow :)

There actually was one :)
Here is another one;
Extending the usecase already given; we have a user with 3 layers.  He 
creates a selection around an item in the document. Like a trafficlight. 
He then uses that over the 3 different layers to paint in the alpha layer 
with a low density brush and get just the right balance of the different 
items from the different exposures.

And one from personal experience;
Take a photo with an elk; then create a mask around an animal so thats the 
only thing you see on that layer.
Besides using that elk itself ones or twice I want to do a theme and I 
want to have that same outline recurring in the picture itself but then 
all black.  So I create a selection based on the transparancy of the 
layer that holds my elk.
I create a new layer and use the selection to fill one or two elks in 
different places.
