Description:
LO calculates incorrect value for stringAlignmentHorizontalOffset.
It seems to become worse with larger font sizes.

Steps to Reproduce:
Open attached EMF sample.

Actual Results:
LO draws "H Align center H" and "H Align far HHHH" lines progressively shifted
to the left from their expected positions.

Expected Results:
'Align center' string should be centered, 'Align far' string should be right
aligned with the 'scale'.
