And use it for hud_scoreboard_gravity. Putting the enum def in view made
the most sense as view does own the base type and the enum is likely to
be by useful for other settings.
One moves and resizes the view in one operation as a bit of an
optimization as moving and resizing both update any child views, and
this does only one update.
The other sets the gravity and updates any child views as their
absolute positions would change as well as the updated view's absolute
position.
