 *  This has to start as sort of an "interface", while I think about things.
 *
 *  This must handle:
 *
 *	- repaints of itself
 *	- limited paints of itself
 *	- justification (left/right/center)
 *	- internal margins
 *	- caching content-height (as opposed to visible height),
 *	    so things like column-balancing can work ?
 *
 *	- All the nasty little things DocPage previously did:
 *	  Highlight, insert/delete, ... ?
