--- Comment #4 from Jeff Smith  ---
I have done a fair bit of experimenting around this, but I haven't nailed it
down yet. It does NOT seem to rest on the backing context type (for example
graphics->image). It may be something along the lines of the transform applying
to both the region and the point under test, and in some edge cases native's
result is "wrong"... The IsOutlineVisible_Line_WithGraphics test hitting on one
such case.
