[cairo] understanding _cairo_path_fixed_fill_extents()

[Enrico Weigelt, metux IT consult]

Hi folks,

I'm currently trying to understand _cairo_path_fixed_fill_extents().
It checks whether the path's extents box is defined by two points
where the second is south-east from p1. If not (eg. they're in the
order) it just initializes the rect as zero.

What about the north-west cases ? Why are they dropped to zero ?
Shouldn't they just be inverted instead ?
