GdkRectangle vs cairo_rectangle_int_t


Just wondering, why gtk_popover_set_pointing_to() takes an argument of type cairo_rectangle_int_t and not of 
type GdkRectangle? Which one is better suited for each situation? I know one if a typedef of the other, but 
I’m curious and I can’t think of it myself. I guess cairo_rectangle_int_t makes more sense when the rectangle 
is something actually drawn, and GdkRectangle is more general.

Thank you very much.
