The general Plane brush is a replacement for the Flatten, Fill, and
Scrape brushes that formerly existed. When the old brush types were
converted to the new type, the 'Plane Offset' usecase was missed due to
the field not being used for the bundled essential brushes.
To preserve brush behavior across 4.4 and 4.5, Scrape brushes with a
given 'Plane Offset' need to have this signed distance inverted.
Unfortunately, as this was discovered after 4.5 was officially released,
and the versioning having no clear indicators that can be used to fix
this with a subsequent version bump, this commit cannot address users
who have already started using 4.5. The best we can do in this case is
fix the incorrect versioning and make a note of the issue in the release
notes so that future users will not continue to experience this issue.
