The default hardness was previously 1.0f, but the renderer actually used the inverse (1.0f - hardness). Now we store this value directly. This also matches the default for float attributes (0.0f).

If the functionality i would also expect the name to change to "softness".

References to "previously" and "now" tend to get confusing. Better say "Grease Pencil v2" explicitly.

@LukasTonne and I talked about the naming and we agree that if we change it to be inverted, we should change the name in the code to softness too. Otherwise it would get too confusing.

Looks good, I don't think more review is necessary. Agreed that switching the name and variable names to "softness" would be helpful too. And looks like fb6324bdd0 can be reverted too.

Since the plan changed to go back to the current renderer, closing this for now.

I think this is still worth doing. It will get harder after the initial release because of versioning.
It would only be a 1.0f - softness in the drawing extraction code for now anyway.
