apply magnet during the drag operation

[cmsImagine]

Would it be possible to add something like this so while dragging the bars they snap the the magnet values instead of resizing to the magnet values in dragEnd ?

If you think this would slow down drag events too much could the callback event be modified so the callback can modify the value?

Hey there! Thanks for your PR! Sorry I didn't have the time to go through it yet, but it sounds promising!
