docs: Add details
...
Spell out what gsk_path_point_get_tangent does
if there is no tangent: we return 0,0.

Improve precondition checks for path points
...
Add a helper function for checking that a
path point is valid for a path, and use it.

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

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.

pathpoint: Add some debug API
...
Add a private gsk_path_point_to_string that
can be called in the debugger if you want
to see the contents of a GskPathPoint and
are too lazy to cast it to GskRealPathPoint
yourself.

gsk: Add GskPath
...
This commit adds the basic infrastructure for paths.
The public APIs consists of GskPath, GskPathPoint and
GskPathBuilder.
GskPath is a data structure for paths that consists
of contours, which in turn might contain Bézier curves.
The Bezier data structure is inspired by Skia, with separate
arrays for points and operations. One advantage of this
arrangement is that start and end points are shared
between adjacent curves.
A GskPathPoint represents a point on a path, which can
be queried for various properties.
GskPathBuilder is an auxiliary builder object for paths.
