Remove heads up panel translation.

The only time I got a non-zero translation was RTL orientation changes, and it was a transient artifact that caused visual glitches.  The translation was done in the name of alignment, which is no longer a desire of this class.

Fixes: 185679234
Test: manual; especially with RTL and rotation changes.
