Inconsistent width of centered content.

[tecosaur]

dvisvgm processed centred content is sometimes produced with different widths, more specifically: When running on multiple pages, any centred content after the first page is flushed left.

This is apparent simply by looking at the stdout-reported width information.

The fix for #209 should also address this issue.
