I had looked into this a bit already, and have some related patches in my
gdiplus queue that still need a lot of cleaning-up.

In most cases, a repeated point is skipped in Windows.  If the entire path
reduces to a single point, status 3 (OutOfMemory) is returned (and the path is
not altered), just as when a single point is actually provided.

There are a few cases however, that are peculiar and need further
investigation.
