+\fBTk_GetJustifyFromObj\fR caches information about the return

+\fBTk_GetJustify\fR is identical to \fBTk_GetJustifyFromObj\fR except
+that the description of the justification is specified with a string instead
+of an object. This prevents \fBTk_GetJustify\fR from caching the
+return value, so \fBTk_GetJustify\fR is less efficient than
+\fBTk_GetJustifyFromObj\fR.

\fBTk_NameOfJustify\fR is the logical inverse of \fBTk_GetJustify\fR.
Given a justify value it returns a statically-allocated string
