[Unknown Mod][Game] Add a small graphic on the portrait of the players who have already been defeated in the scenario information screen

[LeHerosInconnu]

In the scenario selection window, the graphics for opponents and class are composed of gray tones to indicate that these components are fixed and cannot be changed.
During the game, the scenario information window does not conserve this graphic composed of gray tones for the class (the graphic composed of gray tones is used to indicate that a player has been eliminated from the game).

In fheroes2:
Scenario selection window:

Scenario information window:

This change conserve these graphics composed of gray tones and add a small graphic on the portrait of the players who have already been defeated (they are no longer in the game) in the scenario information screen.
The graphic will be described later.

This is not an option.
This can be implemented directly in fheroes2.
