The patch looks good to me. I agree with making user the default even
though cairo has defaulted to "pt" historically. Regarding using the
abbr versions of the units rather than full strings I could go either
way on myself, and have no arguments against using the short versions;
anyone dealing with SVG document syntax should be adequately familiar
with the abbreviated versions already.

If no one raises any further qualms within the next few days, I'll go
ahead and land this patch.
