-Shared display object containers used if text not being clipped and container is BasicLayout
-SimpleText will recycle text lines if the player supports it (>= Argo)
-SimpleText now supports truncation. -1 means fill box and truncate if overflow. 0 mean no truncation. >0 is the number of lines to keep before truncating.
There is one issue with textLines being composed with x=0 and textWidth=-number which isn't reflected in the bounding box for either SimpleText or RichText so the text isn't clipped properly. (kerning=on and trackingLeft=-10 demonstrates this).
