Problem description: Not so much a problem as a suggestion. When assigning the incident angle you have to drag the light source. This makes it REALLY difficult to get an angle exact to the tenth. I mean it is really hard sometimes. It would be SO much easier to be able to type in the angle.

Steps to reproduce: Try to drag the light source to exactly 10.0 . It skips between 9.9 and 10.2 mostly but flashes 10.1 and 10 intermittently. Eventually, if you are lucky, you can get it to stop at 10.
