The Enhanced Text Widget
------------------------

Interactions with other code:

"syntaxColouring.tcl" --

'$coloring' is used as a global flag

the win::Modes and win::tktitle arrays are used to find the mode of the
window, and then various colouring variables are looked up in the $mode::
namespace.  (These mostly set by regModeKeywords)

"enhancedTextWidget.tcl" --

global variables: horScrollBar blockCursor tabSize colorInds wordWrap
fillColumn autoSave changesLim indentOnReturn wordBreak wordBreakPreface

procedures called: bind::IndentLine

(also 'useMultilineSearchRoutines' but that's ok).
