Is there some better way to communicate this so that it isn't possible for
chromeos and chrome to get out of sync?

Actually this is inaccurate. We have new cursor images from Alex with hot points
shown in the image. I have updated the comment. I think best way to do this
would be to define hot points in cfg files checked in where the cursor images
are (ui/resources/aura). If you think thats ok, I can do that in a followup CL.
My concerns was if its worth increasing the resources just for the hot points.
