/*! @brief Default frame window for CTreePropSheetEx sheets

  This class is based on CPropPageFrame. It differs in 
  the following:
  - Reduced flickering by using double-buffering. This is 
    especially noticeable in the gradient portion while 
    resizing.
  - Draw gradient using GDI GradientFill or original owner
    drawn gradient (compile time switch).
