//	Wrapping Modes
//
//	Text can be wrapped in one of the following three ways:
//
//		wrapMode_WrapToFrame - Wrap to view frame.  This is similar to common
//			TE style wrapping.  
//
//		wrapMode_FixedPage - Don't wrap.  This would be like the metrowerks
//			code editor in which the page size is arbitrarily large in width
//			but no wrapping will occur when text flows outside the page bounds.
//
//		wrapMode_FixedPage - Text is wrapped to the width of the page.  This
//			would be like a word processor.
//
//		wrapMode_WrapWidestUnbreakable - The page size is determined by
//			the view frame size or the width of the widest unbreakable run.
//			This behaviour would be most like an HTML browser.  Text can
//			always be broken, but things like graphic images can not.
//			With text only, this behaves like the normal wrap to frame mode.
//
//	IMPORTANT NOTE:  if you are providing multiple views on a text engine,
//		and those views have different wrapping modes, the formatter will
//		reformat the text to the mode specified by the view EVERY TIME THE
//		VIEW IS FOCUSED.  This is probably not something you'd want to have
//		happening in your app.
