Re: [PATCH resend] gdi32: Skip edge processing when the area is empty.

[Gabriel Ivăncescu]

Apparently there's a problem with overflow in REGION_CreateEdgeTable. 
The function itself checks for overflow and returns 0 in this case, but 
the call site doesn't (that's why checking for it works).

I've submitted a new version along with a test that demonstrates this. 
Without the check, the test hangs.
