orientation of numeric tick labels is not specifiable for AxisLine

Observed behavior:  The baseline of numeric labels is always
horizontal when an AxisLine is added to X-Axis1.

Desired behavior (first choice):  The AxisLine object should
have a Text tab just like a full-fledged Axis would, allowing
the orientation to be specified independently and directly.

Desired behavior (second choice) The AxisLine object could
perhaps have its orientation locked to the orientation of
the parent X-Axis object.

A graphic is attached that should let you see what I'm trying
to do, and why.  The X-Axis numerical labels are in black near
the bottom, and have their baseline running vertically, as
desired.  Meanwhile the AxisLine labels are in black near the 
top.  They really ought to be oriented with their baseline 
vertical, but there is AFAICT no way to accomplish this.

I searched for similar bugs without finding anything.
