cairo script

This is the minimum cairo-trace/script that I obtained.

To crash it I compiled util/cairo-script/csi-replay.c after
changing the #define SINGLE_SURFACE to 0

To derive a test case from it probably it is possible
to use a smaller surface size.

Enabling xlib-xcb prevents the crash, probably another code path
is executed. (Valgrind (--enable-valgrind=no) reports an invalid 
read though)</pre>
