// decoding command types from argument floats when looking in our
// SVGPathData's data array! Either way, we'll likely then go down
// NS_NOTREACHED code paths, or end up reading/setting more bad memory!!
// The only time that our other DOM list type implementations remove items is
// if those items become surplus items due to an attribute change or SMIL
// animation sample shortening the list. In general though, they try to keep
// their existing DOM items, even when things change. To be consistent, we'd
// really like to do the same thing. However, because different types of path
// segment correspond to different DOMSVGPathSeg subclasses, the type of
// items in our list are generally not the same, which makes this harder for
// us. We have to remove DOM segments if their type is not the same as the
// type of the new internal segment at their index.

// all the items in the new list checking types anyway, that's almost
// insignificant in terms of overhead.

// and we have no way to short circuit the overhead since we don't have a
// way to tell if the call is due to a new animation, or a resample of an
// existing animation (when the number and type of items would be the same).
// (Note that a new animation could start overriding an existing animation at
