    + Added: some methods used internally to provide hbIDE speed advantage.

  * contrib/hbide/idesaveload.prg
    ! Changed: the default behavior of :lTrimTrailingBlanks to FALSE
      responsible to strip trailing blanks from saved sources.
      Now if this behavior is desired, change the settings from 
      <Setup><hbIDE Setup><General>.

  * contrib/hbide/idethemes.prg
  * contrib/hbqt/qtgui/hbqt_init.cpp
    + Added: Slot "QRect$int" for updateRequest(QRect,int) for QPlainTextEdit.

  * contrib/hbqt/qtgui/qth/HBQPlainTextEdit.qth
  * contrib/hbqt/qtgui/qth/HBQSyntaxHighlighter.qth
    + Added: more methods.

  * contrib/hbqt/qtgui/hbqt_hbqplaintextedit.cpp
    ! Fixed: 2 pixel margin around a document text which was causing a 
      major visual glich which selecting text in an editing instance.
      Now it is 0,0 no matter which font and size is used.

  * contrib/hbqt/qtgui/hbqt_hbqplaintextedit.h
  * contrib/hbqt/qtgui/hbqt_hbqsyntaxhighlighter.cpp
  * contrib/hbqt/qtgui/hbqt_hbqsyntaxhighlighter.h
    + Synchronized: to apply syntax highlighting per page basis.
      Qt applies highlighting to the entire document when supplied 
      which, conceptually, should be onto the page brought forward.

      This has rendered hbIDE extremely fast at startup no matter 
      how many sources are loaded probably making hbIDE the fastest 
      IDE at startup.
