A similar issue is described here in
https://bugs.freedesktop.org/show_bug.cgi?id=20091

Pixman restricts its input to 16.16 fixed point, so the pixman-based backends
(image, xlib, xcb) currently fail to produce the correct output when using big
input paths.

The correct approach would be to keep the path with arbitrary precision, then
clip it before rasterizing/passing it to pixman.
