Ray collision fails when origin in a face

Hi,

When I cast a ray with origin point inside the face of a Mesh, it won’t detect a collision. Quick example (a modified version of examples/canvas_interactive_cubes.html from r45): https://gist.github.com/1366114

Noting that,

var V = THREE.Vector3;

changing the line 159 of the gist, from

var origin = new V(20, 20, 20);

to

var origin = new V(19.5, 19.5, 19.5);

shows that the collision will work fine.

@kevanstannard Seems to be. Thanks!

@mrdoob do you think this might be resolved now? I created a simple test and it seems to be working correctly, but not sure if I understood the original problem properly.
