It's already in there.

from cairo.h:

/* Rectangular extents */
void
cairo_stroke_extents (cairo_t *cr,
            double *x1, double *y1,
            double *x2, double *y2);

void
cairo_fill_extents (cairo_t *cr,
          double *x1, double *y1,
          double *x2, double *y2);


Getting object bounding coordinate units working with libsvg-cairo would
be great, a lot of svgs are using those, especially for gradients.
Another thing that's supported by cairo but not yet added to
libsvg-cairo is gradient matrix support.
