I encountered what I think is a bug with cairo when drawing with
push_group/pop_group, OPERATOR_SATURATE, rotated, to a PDF surface. I am
drawing rectangles next to each other.

On cairo 1.8.10 (Fedora 13) I get strange seams unless I clip and CLEAR
within the group. cairo 1.2.4 (RHEL 5) has no such problems.

I am including a python test program. Output from both programs are here:
