Point is clear: WS must draw controll, after that you must be able to do some 
custom paints over it, or you can completely draw control.
Some time ago I've thinking about adding 2 flags into TWinControl 
TControlStyle - csOwnerDraw and csOwnerDrawFull. They are valid only for ws 
controls which are fully painted from widgetset.
1.csOwnerDraw - control is painted by ws but after that paint message is 
delivered to LCL, so you can edd eg. small red triangle in TEdit corner.
2.csOwnerDrawFull - control is fully drawn by you, when an paint event occurs 
it's delivered to LCL, but stopped for ws, so it won't do any additional 
paintings.
