GTX780 ti (368.69)
Broken: 2.78.4 9f67367
Worked: official 2.78 e8299c8
Short description of error
Using scene.raycast() in python is not working anymore. I don't see any update in the doc, truly sorry if it's not a bug.
Exact steps for others to reproduce the error
Open the file ray_cast.blend, run the srcipt, launch the operator "TestRayCast" in the tabs.
It should return the name of the object and a bgl circle under the mouse if an object is find, but nothing happend.
