-Subject: clip: consider all_clipped in _cairo_clip_get_extents
-
-If the gstate clip in _cairo_gstate_int_clip_extents() has all_clipped
-set (and path NULL), then it returns the gstate target extents instead of
-an empty rectangle.  If the target is infinite, then it says the clip is
-unbounded.

-Fixes https://bugs.freedesktop.org/show_bug.cgi?id=29124
-Tested-by test/get-clip
