In this present case, I could see the bound info being calculated via a 
callback that fetches the 'quantized position property for the Y values, but 
the X values would still need to be calculated by consulting the normal stems à 
la lines 559-570.  Were I to place the calculation in a callback, it would 
require a code dup of these lines.  To avoid this, I could create a property 
called x-positions and change the name of positions to y-positions and 
quantized positions to quantized-y-positions.  Then, I'd put lines 559-570 in a 
separate callback for the X positions.  Lemme know if this sounds good.
