Cleanup: minor edit to last commit

Avoid repeating the fallback return.

Fix T73348: Surface Deform distortion on bind with small faces

Thanks to @CodyWinch for finding the root cause

Merge branch 'blender-v2.82-release'

Fix T73682: Sampling color fails for float images

Fix T73695: line highlight jitters with smooth scroll

UI: Use popup dialog for make single user from operator search

Use a popup since the default action was to do nothing,
the user would always need to access the redo panel.

Resolves T73711.

Fix T56108: Crash editing corrupted vertex groups

While the file in this report had corrupted values,
this is avoidable without adding any extra overhead.

Use unsigned vertex group indices since we don't need negative values,
this is an alternative to checking they aren't negative in many places.

Vertex group values over INT_MAX is still considered invalid,
so any accidental unsigned wrapping won't be silently ignored.

Cleanup: remove duplicate, commented structs

Cleanup: extra semicolons, comma use, undeclared vars

Cleanup: unused headers

- Address reviewers comments

Cleanup: add license header, use header guards

Doc: update to T73699 fix

It's important to refer to "other selected objects" in this case.

Doc: simplify T72883 fix

Code example made it seem setting the active object was more complex
than a single assignment.

RNA: Raise error assigning an active object which doesn't exist

Previously this silently cleared the view layers active object.

GPencil: Refactor: Add implementation of new mask list system

This system makes it possible to have up to 256 layers in a GPencil Object
that can be used as masks. User can use more than 256 layers and use mask
on them but the masking one must be from one of the first 256.

This commit does not include optimizations.

Fix T72883: Correct Context Usage

Fix T73699: Unhelpful error message when trying to knife project a manifold object

Fix T72690: Do not draw points behind the viewport camera in the paint cursor

In some situations the symmetry point may be behind the camera, so the
projection is inverted and it looks wrong. This avoids drawing points in
screen space when they are behind the camera.

Revert "Sculpt: Remove partial viewport updates from sculpt stroke code"

This reverts commit 394b48029c5335381f774f83524ad6ee5cb986da.

Leaving this here does not affect performance in any significant way and it may be useful in the future.
