     **                  GUI mode ignoring SESSION:DATA-ENTRY-RETURN value.  The combo-box does not
     **                  react to the ENTER key in GUI.  Key processsing fixes for GUI mode.
     ** 014 EVL 20151120 Fix for drop-down line spacing issue. And fix for button incorrect drawing
     **                  over 3d border.
     **                  over 3d border.  Drop-down button fix for pressed state drawing.  Pressing
     **                  the drop-down button need to be painted accordingly.

     ** 010 EVL 20151010 Fix for thumb drawing issues. Also reworked image loader specifically for

     **                  these cases we do not need to repaint whole window.
     ** 011 EVL 20151124 The button pressed state needs repaint() call to properly display pressed mode
     **                  when running indide drop-down life cycle.  Improved mouse handling, in 4GL
     **                  if to press mouse, move inside button and release - this generates click.  So
     **                  we have to track the mouse release, not click.  Adding auto-scroll feature on
     **                  press and hold mouse button.
