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
