This is hopefully a really simple question, but I'm having trouble getting a clear idea from the code...
What's the difference between 'objects' and 'elements' in Three.js?
For example, in Projector.projectScene( scene, camera, sortObjects, sortElements )
. And the flags 'sortObjects' and 'sortElements' in the CanvasRenderer. I understand what they do collectively, but what's the difference between them / why are they separate flags?
