2e24a9ece4 Make GskPathPoint public 
The contents are still /*< private >*/, but we
let our tests and the debugger see them, which
helps.

2a17320314 Limit rect variation in path builder 
Make gsk_path_builder_add_rect always
produce a clockwise rectangle. This matches
what we do for circles and rounded rects,
which also go clockwise. Note that we
still need to allow negative widths in
the contour code, to implement reverse().

0dbff14555 Allow circles with radius of zero 
Not very useful, but we allow rects with
width and height of zero, so lets be consistent.
Curvature is infinite for such contours.

Tests included.

2ca9982b91 rect contour: Avoid nans in corner cases 
The length of rect contours can be zero,
so we much check before we divide.

ad9fb1e101 Improve quad and conic decomposition 
If the control point is equal to either
start or end, just emit a line. This improves
the rendering of rounded rectangles with such
corners.

have for the other special contours.

78c5aff956 Test special contours harder 
Check that the start- and endpoint work
as expected and verify that their winding
numbers match the ones of the standard contour,
and are negated when the contour is reversed.

cee043f977 Add a rounded rect contour 
This special contour takes advantage of its

boxes and winding numbers. It falls back
