[cairo] Extending Cairo API to support reusable paths

As part of my internship at Mozilla, I'm working on extending the Cairo
API to allow caching of reusable path objects.
On the default backend, these will directly wrap the current
cairo_path_t objects, and their related functions.
However on Quartz we can include a copy of the CGPath object and on
direct2d a copy of the ID2D1Geometry to hopefully increase redraw
performance on these platform.
The API changes I am proposing are:
/* New cairo API */
typedef struct _cairo_retained_path cairo_retained_path_t;
cairo_public cairo_retained_path_t *
cairo_append_retained_path(cairo_t *cr, cairo_retained_path_t *path);
Does anyone have any thoughts, questions or suggestions on this?
