4bea7bca1f path: Implement gsk_path_parse 
Implement the SVG path syntax to read back the strings
that we generate when serializing paths. The tests for
this code are taken from librsvg.

This includes an elliptical arc implementation according
to the SVG spec. The code is mostly taken from librsvg,
but pretty directly follows the SVG spec implementation
notes. We don't export this, since the parametrization
is inconvenient. We do want an arc_to API, but
these are not the arcs we are looking for.

It will be used in parsing SVG path syntax.

aaa2a405a4 stroke: Add miter limit 
Add a miter limit to GskStroke. This will be needed to
fully implement line joins.

Also introduce the GSK_LINE_JOIN_MITER_CLIP value,
following SVG 2.0. cairo does not have it, so translate
it to plain miter when using cairo.

fe307f03c5 pathbuilder: Redo semantics for starting curves 
We now always have a "current point" which is either the last point an
operation was made to, or (0, 0) if no drawing operation has
been made yet.

Adding a contour of any kind to the builder will always update the
current point to that contour's end point.

44e55c1067 testsuite: Update create_random_path() 
1. Allow specifying the max number of contours
2. Be smarter about creating the paths:
   With 10% chance, create a "weird" path like the empty one or only
   points or things like that.
   Otherwise create a bunch of contours, with 2/3 a standard contour,
   with 1/3 a predetermined one.

84f45d4282 path: Change data structure for standard path 
Instead of the Cairo method and imitating cairo_path_data_t, use the
Skia method and keep points and operations separate.

That way we get a points array that includes the starting point -
because it's always the end point of the previous operation.

1b2a79f1d1 mediafile: Load extension at startup with GTK_MEDIA 
When the GTK_MEDIA env var is set, check at startup that it works, not
only when the first MeidaFile is instantiated.

This has the fortunate side effect that it prints help output for
GTK_MEDIA=help at startup, too.

Checkout the drag threshold only makes sense when starting a scroll, after
that it just adds jumps when trying to scroll back and forth.
