LayoutManagerDemo

=================

ABOUT:

 This application demonstrates interrogating the layout manager for information about   text layout, and the use of temporary attributes to color text.  Specifically, we provide rollover coloring of text--one color for the line, another for the word,    and a third for the character under the mouse.  A subclass of NSTextView is used,   but solely for the purpose of obtaining mouse events.  The interesting portion of    the code involves the conversion of mouse coordinates to a particular glyph and   character index, then determining the corresponding line and word, and finally    using temporary attributes for coloring.
