Subject: fixed pres hide before/after, select w/o nav, and updating contents..
 made collections fitWidth by default so that they resize like a normal
 window. Made freeform pan/zoom animate when changing keyframes.  allow
 nesting of keyframe collections..  made presEffects work even if there's no
 transition movement. made nested collection timelines follow parent by
 default, but with ability to change ordering.  fixed treeView incremental
 render.  treat doc anchors are preselements instead of delegating. don't
 highlight ink when dragging ctrl pts.
