[BUG] dataset pointRotation option not working

[havardthom]

The pointRotation option in datasets does not seem to be working.

Expected Behavior

In the jsfiddle example I'm expecting the triangle to be rotated downwards (180 degrees) and the rectangle to have a slight angle (20 degrees),

Current Behavior

No rotation is applied.
