Prisms get away from the mouse

[samreid]

Noted in master: go to 2nd screen, drag a prism from the toolbox. Depending on your screen size, the prism will go faster than the mouse.

Still happening to this day.

Observed again today. This would block republication.

Found again today while testing phetsims/qa#226. Assuming it is unrelated due to the age of the issue.

Sounds like an incorrect coordinate transform in a drag handler, maybe confusion between globalToParentPosition and globalToLocalPosition (or something like that...)

Found again during ES6 Testing

Unassigning until I return to bending light.

[samreid]

I tested master in a wide variety of screen sizes, and tried dragging prisms from the toolbox and in the play area. Nothing got away from the mouse. I'm not sure how this was corrected, but I don't see obvious commits in bending-light that would explain it. Closing... (for now?)

Reopening based on the 3 TODOs marking this issue in the code, they seem like they need attention.
