XPoint                                                         [typedef]
        This is the data  structure used for  defining positions. It  is
        defined as follows:

            typedef struct {
                short x, y;
            } XPoint;


XRectangle                                                     [typedef]
        This data type defines rectangles.

            typedef struct {
                short x, y;
                unsigned short width, height;
            } XRectangle;
