Calculates the intersection of two rectangles.

x1 :

 origin of first rectangle

y1 :

 origin of first rectangle

width1 :

 width of first rectangle

height1 :

 height of first rectangle

x2 :

 origin of second rectangle

y2 :

 origin of second rectangle

width2 :

 width of second rectangle

height2 :

 height of second rectangle

dest_x :

 return location for origin of intersection (may be NULL)

dest_y :

 return location for origin of intersection (may be NULL)

dest_width :

 return location for width of intersection (may be NULL)

dest_height :
