My (uncommitted) patch turns 1483 calls to PathGeometry::ComputeBounds into 46
calls. Still those mere 46 calls manage to call PathFigure::ComputeBounds 7348
times; and that "degenerates" into:

* cairo_bentley_ottman_tessellate_polygon being called 7077 times (12%);
* cairo_bo_sweep_line_validate being called 129,876,580 times (23%)
* cairo_bo_event_compare_pointers being called 1,602,767,429 times (9%)
* (cairo) _sweep_line_elt_compare being called 569,711,944 times (5%)
* list goes on...

there's a lot of polygons in there!
