	EFX_FRAME_OUTER_RAISED	[0x0010] Outer band raised
	EFX_FRAME_ADJUST_RECT	[0x0100] Adjust dimensions of the destination rectangle
uFrameWidth	Middle band width.
crFrame	COLORREF value that specifies the middle band color.
uInnerWidth	Inner band width.
crInner1	COLORREF value that specifies the inner band shadow color.
crInner2	COLORREF value that specifies the inner band highlight color.
uOuterWidth	Outer band width.
crOuter1	COLORREF value that specifies the outer band shadow color.
