Hi,
This is a new version of my test for bug 4543. This time, I followed Dmitry's suggestion of using the existing functions for comparing the contents of EMFs. I can't build tests for Windows both due to bug 20763 and due to the fact that I don't have any Windows boxes, so once again I need people to run this test on Windows to make sure it's an accurate representation of Windows' behavior. The test currently succeeds on Wine.
Thanks in advance.
Chip
