gdk-drag-find-window-for-screen (context window screen x y)

context -- a gdk-drag-context object
window -- a gdk-window object which may be at the pointer position, but should be ignored, since it is put up by the drag source as an icon
screen -- the gdk-screen object where the destination window is sought
x -- an integer with the x position of the pointer in root coordinates
y -- an integer with the y position of the pointer in root coordinates

dest -- the gdk-window destination window
protocol -- the gdk-drag-protocol DND protocol

Finds the destination window and DND protocol to use at the given pointer position. This function is called by the drag source to obtain the destination window and protocol parameters for the gdk-drag-motion function.
