/*! @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).
