/* FIXME:
 * 
 * things to add:
 * 
 * * jump/align to spot (N spaces, N pixels, N% (set or adjust by +/-))
 * * left and right margins
 * * anchors (for inline objects other than text - images etc.) - variable size ones too
 * * if a word (or char) doesnt fit at all do something sensible
 * * freeze thaw api
 * 
 * tough ones:
 * * directly accessible text spans (so you can track where that span is, how big it is after many inserts/deletes) and modify its formatting etc.
 * * overflow objects (overflow from this textblock can go into another)
 * * on change figure out what node the change is in and figure out what line (nodes) it affects and only modify those nodes on that line or maybe others until changes dont happen further down
 * * obstacle objects to wrap around
 * * kerning control
 * * fully justified text (space chars evenly to fit the line)
 * * if a word spans 2 layout nodes with no whitespace, it should not be splittable.
 * 
 * really tough ones:
 * * fix core text code to properly handle unicode codeponts - handle ALL unicode domains properly.
 * * right to left text
 * * top down (japanese/chinese) text layout
 * 
 * insanely tough ones:
 * * for ultra-huge documents determine paging sections of the text in/out and being able to provide callbacks form the user api that can provide the text
