Computes a bounding box in user coordinates covering the area that
would be affected, (the "inked" area), by a cairo_fill() operation
given the current path and fill parameters. If the current path is
empty, returns an empty rectangle ((0,0), (0,0)). Surface
dimensions and clipping are not taken into account.
Contrast with cairo_path_extents(), which is similar, but returns
non-zero extents for some paths with no inked area, (such as a
simple line segment).
Note that cairo_fill_extents() must necessarily do more work to
compute the precise inked areas in light of the fill rule, so
cairo_path_extents() may be more desirable for sake of performance
if the non-inked path extents are desired.
See cairo_fill(), cairo_set_fill_rule() and cairo_fill_preserve().
