SetRect and OffsetRect are two entirely different operations.

SetRect fills the fields of a rectangle with values, to initialize it. If you
try to use OffsetRect on an uninitialized rectangle, you get garbage. 

OffsetRect is useful for moving a rectangle by a certain distance
horizontally and/or vertically; the same thing could be achieved by adding
the offsets into all fields of your rectangle:

	{
		r.top += voffset;
		r.bottom += voffset;
		r.left += hoffset;
		 r.right += hoffset;
	}


 I would suspect that OffsetRect does much the same thing, so the efficiency
gain by using OffsetRect versus the above 4 lines of code is minimal, if
there is anything. 

To rehash: use SetRect to initialize a rectangle (or you could fill the
fields by hand, it's only a difference in readability. To move a rectangle,
use either OffsetRect (for readability), or else use those 4 lines of code
above...

Hope this helps out.
