True. '0 INVERT END' may be allowed as a syntactic convenience to authors.
Or 0 INVERT could be rewritten as
0 INVERT [ON|OFF|TOGGLE]
where TOGGLE would be the default action.

0 INVERT is different from 0 FACE [CW|CCW] in a couple of ways:
- 0 INVERT affects subfile commands. 0 FACE affects triangle and quad
commands.
- 0 INVERT is passed through to subfiles. 0 FACE only affects the current
file.
