Source position: types.pp line 334
function PtInRect( 
const Rect: TRect; 
const p: TPoint 
):Boolean; 
PtInRect returns True if p is located inside Rect, and False if it is located outside the rectangle.
Remark:  Note that the bottom, right edges are not considered part of the rectangle, therefor a point located on one of these edges will not be considered part of the rectangle, meaning that for a record (10,10,100,100) the point (90,100) will not be considered part of the record, but 90,10 will be.
