--- Comment #6 from Jeff Smith whydoubt@gmail.com --- FYI, I boiled down the failing IsOutlineVisible_Line_WithGraphics test to a GdipIsVisiblePathPoint test and see the same quirk on native with both, which I take as confirmation of GdipIsVisiblePathPoint being where the fault lies. I have run across some other quirks as well, but have yet to find the pattern in the noise.
If GdipIsVisiblePathPoint matched, I suspect everything up the stack would match as well.
