Function: GetRectIntersect
Params: var DestRect: TRect; const SrcRect1, SrcRect2: TRect
Returns: Boolean
Intersects SrcRect1 and SrcRect2 into DestRect.
Intersecting means that DestRect will be the overlapping area of SrcRect1 and
SrcRect2. If SrcRect1 and SrcRect2 do not overlapp the Result is false, else
true.
