9ffd7840ba pathpoint: Add G_GNUC_EXTENSION to struct definition 
This allows compilation with gcc -pedantic.

GTKmm uses this as part of their recommended compiler flags.

Fixes #6083

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

e1faf28310 Make curvature api more flexible 
Add an extra direction argument to get_curvature to
allow picking the limit on either side, for sharp turns.

Update all callers.

6ace4b60d8 pathpoint: Revise argument order 
In order for introspection and documentation to
not be confused, we need to have the GskPathPoint
be the first argument.

Update all callers.

1b5dfcba7e 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.
