The most important difference is that frames are now transparent.
Painting engine was optimized, should be now faster.
Following complicated Ctrl virtuals are now gone:
virtual Vector<Rect> GetTransparentFrameRects();
virtual Vector<Rect> GetOpaqueFrameRects();
virtual Vector<Rect> GetTransparentViewRects();
virtual Vector<Rect> GetOpaqueViewRects();
replaced by simple
virtual Rect GetOpaqueRect();
which can simply return the opaque view rect (and painting engine uses that value to optimize drawing). Default implementation is
Rect Ctrl::GetOpaqueRect()
{
return IsTransparent() ? Rect(0, 0, 0, 0) : GetSize();
}
