Ah, you wont find it w/ a simple grep, as the situation is a bit more
complex (took me a while to sort that out):

In older versions, the composite_polygon_info_t had a callback vector,
which had been initialized to one of the *_add_polygon() functions.
That's gone for quite some time.

As the _composite_polygon_spans() functions of the i915 / i965 create an
cairo_botor_scan_converter_t, I've guessed that it's *_add_polygon()
function needs to be called here.

The actual changes to call it are done in subsequent patches.
