Set width of ProgressDrawTargetKind::Hidden to 0
Set width of ProgressDrawTargetKind::Hidden to 0

Arguably, it makes a bit more sense than 79. It doesn't change any
behavior because hidden progress bars are never rendered (and only then
is width used). If rendering did occur with hidden progress bars it
would make rendering a tiny bit more performant. This is an
internal only change as width isn't exposed to
downstream users.
