Adventure map, display terrain and object information even when a hero is positioned on an object

[LeHerosInconnu]

When a hero is positioned on an object, it is not possible to get information about this object in relation to another hero.
Also, it is not possible to get information about the terrain under a hero or under an object.

In fheroes2:
Info from the Witch Doctor Hut's in relation with the selected hero Roxana.

The hero Celia is positioned on the Witch Doctor Hut's; it is not possible to have the information of the Witch Doctor Hut's in relation to the selected hero Roxana.

To get the information, the player can cycle through the different information by using the mouse wheel down while holding down the right mouse button (each click of the mouse wheel down changes the information displayed).
(Also by pressing the "CTRL" key on the keyboard while holding down the right click, each press changes the information displayed.)

In the example, a first click of the mouse wheel down displays the information of the Witch Doctor Hut's, a second click of the mouse wheel down displays the information of the terrain (here the Swamp), a third click displays again the information of the hero Celia, etc.
Similarly, if the hero Celia was not positioned on the Witch Doctor Hut's, it would also be possible to get the information from the terrain with the same operation.
