The resolved arguments when the symbol is constructed with none (null for symbols not in lib)
Length of its timeline in frames
The filterCacheList the symbol's constructor sets on the instance itself
(null if it sets none). It takes effect only while AdobeAn.handleFilterCache
is attached to the instance as a tick listener, which whoever creates the
instance does (see ISlotDef.filterCacheListener)
The bounds of each frame (frameBounds), or null when not published
The symbol's drawings as indexes into the content's graphics: the
drawing a shape slot or a tween value calls n is graphics[this.graphics[n]]
The key of the symbol in the published lib (used as is, including
non-ASCII names). Symbols that are not in lib (a bare createjs.MovieClip
created inside a constructor, or a class the content never registered)
get an id starting with #.
The kind of symbol
Frame labels of its timeline
Instance names the constructor sets (this.<name>)
The bounds published on the symbol (nominalBounds), or null
The slots, by template and initial values
In timeline order (the order decides stacking)
Slots added as children without being driven by the timeline
A MovieClip symbol whose slots are templates, whose drawings are in the content's table and whose tweens write each value once.
