Describe the bug
a clumsily packed conglomerate does not update its facings when a block that is part of the packing, gets replaced in level editor with overwrite ([INS]) mode on.

To Reproduce
Steps to reproduce the behavior:

1. Make a clumsy pack of Mauer
2. Turn overwriting on by pressing the [INS] key
3. Select another dings from the HUD (same default layer)
4. Command a "place" on an existing Mauer of the pack

Expected behavior
The pack should reroute, assuming a "Shy" facing for the intruder.

On the start screen, right and bottom areas are not populated by GoL cells. It looks like the GoL plane was smaller than the client area of the viewport.

Steps to reproduce the behavior:
Start the application exe in restored window mode.

Expected behavior
Startup GoL animation creates a plane that covers the entire viewport, so cells would appear also in the right and bottom areas of the screen.

• OS: Windows 10

(b) only chain their update() when they are actually shown and not paused.

Collision detection glitches in the Y direction: player teleports through walls.
Use left/right working code (east/west) in Player.cpp as the basis to fix the logic for the Y variable.
