Please describe the problem:
When right-aligning a text with style="text-anchor:end", the text may not really be consistently alligned, when letter spacing is altered in the line, for example with "font-style:bold". The problem is much more pronounced when bold and normal styles are mixed inside a text element.

Steps to reproduce:
Test file alignment_test.svg and EOG output alignment_test_eog.png will be attached. First and fourth line: correct right-side alignment with vertical line. Second and fifth line: Slight displacement to the right. Third and sixth line are off for almost 0.5em.

Actual results:


Expected results:
Inkscape and Mozilla both show consistent alignment of all lines

Does this happen every time?
Yes. This even holds true when uploading files to Wikimedia.
