Weight gradient operator didn't respect hidden vertices. Now fixed.

Nice improvement, but this will crash when there is no .hide_vert attribute. Also, the custom data lookup should happen once rather than for every index.

I see, thanks!

It's inside the callback, so I guess I'll check before this is called and store the array inside WPGradient_userData to make it available inside the callback.

Initiated the VArray for .hide_vert outside the callback.

BKE_attribute.hh includes BLI_virtual_array.hh indirectly, no need to add it here separately.

@lichtwerk In the issue you mentioned there's still inconsistency with image painting. What I understood there is that the user should not be able to paint inside a UV region where the corresponding face is hidden? (Or not?) I think the intention is to merge this PR and take care of those later?

Hm, I was thinking to make this a bit more general (since like I mentioned in #106354 a lot of other operators are affected as well...), but also fine for me to have this in and improve more later.
