    Optimise d3.mean.

    Originally we were using Welford’s algorithm, but this is primarily
    useful when computing the variance in a numerically stable manner, since
    Welford’s approach requires an incremental mean.
    
    I’ve removed a test for the mean of more than one instance of
    Number.MAX_VALUE as this is unlikely to occur in practice; most likely
    this was the reason I used Welford’s algorithm in the first place.
    
    There’s a paper [1] comparing various algorithms for computing the mean,
    and Welford’s is actually slightly less accurate than the naïve
    approach.  There are some more accurate approaches but I think it’s
    overkill for d3.mean.

    Only coalesce exact string matches.

    If there are a lot of matching numbers, it’s faster to do direct string equality
    comparisons than it is to coerce to a number and compare numerically.

    Don’t generate empty polygons during clipping.

    Fixes #1823; spurious closePath events were being generated for
    degenerate polygons due to generation of empty polygons and rings in
    rare cases.

    Test for interpolate to null.

    I’m not entirely sure this is the most useful behavior, but since typeof null is
    "object" and +null is 0, interpolating to null is equivalent to interpolating to
    the number zero.

    Default to suitable precision.

    The point of this method is to pick the right precision for you!
    authored March 23, 2014
  6. Mike Bostock

    More standard precision interpretation.

    Rather than overload the meaning of precision to bias the selection of the SI
    prefix, always use the standard SI prefix, and use the precision in the same
    sense as with fixed digits: the number of digits after the decimal point.

  7. Mike Bostock

    Consistent SI-prefix for small numbers.

    For reasons that I can’t recall, the SI-prefix behavior was different for small
    numbers (between -1 and 1) than it was for large numbers. This commit enforces
    consistent behavior, so that the coefficient is always in the range [1, 1000),
    like in engineering notation.
    
    For example, the old d3.format("s") would display 0.01 as "0.01", whereas the
    new behavior displays it as "10m".

    Consistent SI-prefix for ticks. Fixes #1746.

    When a SI-prefix format (type "s") is passed to scale.tickFormat, compute a
    suitable SI-prefix based on the maximum value in the range, and then use that
    prefix for all ticks rather than computing the SI-prefix on a per-tick basis.

    Listen to the touch target.

    This ensures that if the touch target is removed from the DOM during a zoom
    gesture, the zoom behavior continues to receive events; touch events, unlike
    other events, are always dispatched to the target of the touchstart event rather than the window.

    Better ticks for subsecond domains.

    Rather than starting the ticks on the minimum domain value, round up based on
    the step size. Fixes #1757.

    Clamp latitude for conic conformal projection.

    The Lambert conic conformal projection extends to infinity along the outer edge
    of the projection, and thus the latitude must be clamped either at -π/2 or +π/2
    depending on the parallels. Fixes #1802.

    Remove workaround for WebKit bug 44083.

    This was fixed in 2010, so I think it’s safe to remove the workaround now.

    d3.touch defaults to changedTouches.

    This way, it’s easier to tell whether the touch changed during the event. This
    also fixes #1600 because the drag behavior now only dispatches a drag event on
    elements that moved, even if multiple touches are active.
    authored March 19, 2014
  18. Mike Bostock

    Add d3.touch; fix #1786.

    The drag behavior no longer crashes when the element being dragged is removed
    from the DOM. In addition, the new d3.touch method extracts a single identified
    touch from the current touch event, making it more efficient during multitouch.
    The drag behavior now assigns touchmove and touchend listeners on the target
    element of the touchstart event, rather than the window.
    authored March 19, 2014
  19. Mike Bostock

    Fix all touches ending on any touch ending.

    The drag behavior registers a touchend listener for each started touch; however,
    a touchend event is dispatched to ALL listeners when any touch ends, not just
    for the corresponding starting touch. The drag behavior must therefore detect
    whenever the ending touch is the corresponding starting touch, and ignore other
    ending touches.
    
    This fixes the drag behavior during multitouch, as discussed in #1786.
