[ANNOUNCE] pixman release 0.17.8 now available

[Soeren Sandmann]

A new pixman release 0.17.8 is now available. This is a development
snapshot leading up to a stable 0.18.0 release.


= Trapezoids =

This release contains a change to the behavior of a1 trapezoids. When
an edge of a trapezoid falls exactly on a sample point, the point now is
considered inside the trapezoid if the edge is a top or left edge,
where before, the opposite rule was in effect.

The new rule is similar to the X11 rule for filled shapes.

If you have an application that depends on these rules, please test
this version of pixman to make sure your application still works.  If
it doesn't, please file a bug at

        https://bugs.freedesktop.org/enter_bug.cgi?product=pixman
