Improved renderQueue performance

doFrame() needs to return true to stop the d3.timer. Also, a new timer was created on each call to doFrame() which slows the animation down as it processes the queue.

Prevent brushing from propagating to reordering

Prior to d3 v3.2.2, the brushstart event would automatically call d3.event.stopPropagation(). When using d3 v3.2.2+ with a plot that's brushable and reorderable, the axes can be reordered while brushing. This change preserves the original behavior.
