CSS has alignment properties for aligning children within a container.
 For a single child, they allow you to align against either side of
the container, or centered in either dimension.

This is something that shouldn't be SVG-specific.  I plan to address
this in the CSS Positioning spec, but that still requires us to
actually define SVG's layout model in terms that are compatible with
CSS's layout models.
