? `ii_maps_callbacks`

This library contains a few functions which are useful in callbacks in mapping applications.

maps_click_stamp(apple, spot, x, y): Selects an area on the screen as if the user had dragged rather than clicked. The width and height are 1/10th of the current map's width.
maps_click_stamp2(applet, spot, x, y): Selects an area representing a map of the next level of mapping. That is an area which can be zoomed to.

maps_click_unstamp(map, spot, x, y): Removes the currently selected are and restores the previous one. Useful in doubleclick callbacks.
maps_click_scroll(map, spot, x, y, step): Scroll in the relevent direction if the click was in a hotspot called north, south, east or west.
