--- Comment #2 from Said Abou-Hallawa <sabouhallawa at apple.com> ---
In general I think using the roundIntPoint() for this assertion does not seem right. For example if we have, rendererMappedResult={2.4999, 3} and result={2.5, 3}, the assertion will fail although it should not.

Maybe we can use something like:

ASSERT((rendererMappedResult - result).lengthSquared() < some_epsilon);

But we may have another bug which makes RenderGeometryMap::mapToContainer() returns inconsistent values.
