Hi,

here is v2 of the path:
https://bugs.freedesktop.org/show_bug.cgi?id=90166#c11

After this is merged we can discuss if some extensions can be useful;
like getting an array of all the possible units, or having a function
to convert the enum values to strings, I mean following the model of 
cairo_svg_get_versions() and cairo_svg_version_to_string().

I was also thinking of tweaking the documentation of the functions which
create SVG surfaces to state that "width" and "height" are assumed to
be in points by *default*, but that their unit can be changed later.

Ciao,
   Antonio
