 The native StyleableStageText and StageText
 controls (and the skins that use them) do not appear to
 support auto-sizing height to multiline content like a
 multiline Label (non-native) control does. 
 Can StageText be configured to
 auto-size vertically to display all content exactly? 
 There appears to be no way to measure
 the text extents of native controls, so I cannot write my
 own logic to size the height. Based on a fixed width and
 font size and family, I need a way to know the width of a
 line of text to calculate the line breaks, but another rub
 is this has to be done with Emoji characters too.
 The reason I need this at all is
 because I need to display Emoji characters the user may
 enter from the soft keyboard. This is a social network-like
 app and Emoji support is required and posted messages cannot
 be of fixed height or lines will be truncated, or there will
 be many blank lines below the content.
 It seems there must be a native
 property that will cause the native control used by
 StageText to auto-size vertically to content and nobody
 thought to expose that property in Flex. I wonder if this is
 accurate enough to open an issue against Flash/AIR and
 possibly Flex to extend StageText to do this.
 Thanks for your suggestions!
