rtfTabLeft is used to indicate the default tab type (left tab).
RTF assumes that if some other type is not specified, a tab is
a left tab and never indicates that explicitly. It's given a
number here so the writer can refer to it by a constant known
to be different from the other tab types. (All "real" token
numbers are non-negative.)
rtfLeaderMotion is used to indicate default tab char (motion only),
which likewise is undefined in RTF.
rtfNoDestination is used to indicate that a state has had no
destination specified yet.
rtfNoBorderType indicates that a paragraph has no borders.
