Here is the pretty picture:

          +-+ +------------+ +------+ +------+
   Label: |x| |     title\/| | Font | |Offset|
          +-+ +------------+ +------+ +------+
 or
          +-+ +------------+ +------+ +------+ +------+ +--------+
   Label: |x| |     title\/| | Font | |VAlign| |HAlign| |Rotation|
          +-+ +------------+ +------+ +------+ +------+ +--------+
 

Workflow:

1. createControl( parent ) - set up controls
2. set( SimpleFeatureType, TextSymbolizer, Mode ) - provide content from SimpleStyleConfigurator
   1. Symbolizer values copied into fields based on mode
   2. fields copied into controls
   3. controls enabled based on mode & fields
3. Listener.widgetSelected/modifyText - User performs an "edit"
4. Listener.sync( SelectionEvent ) - update fields with values of controls
5. fire( SelectionSevent ) - notify SimpleStyleConfigurator of change
6. get( StyleBuilder ) - construct based on fields
