Hi,<br>
<br>
I encountered what I think is a bug with cairo when drawing with<br>
push_group/pop_group, OPERATOR_SATURATE, rotated, to a PDF surface. I am<br>
drawing rectangles next to each other.<br>
<br>
On cairo 1.8.10 (Fedora 13) I get strange seams unless I clip and CLEAR<br>
within the group. cairo 1.2.4 (RHEL 5) has no such problems.<br>
<br>
I am including a python test program. Output from both programs are here:<br>
