/**
Represents a UI window.
Each window has a list of players that are currently using it
When there's no player using a window, it is destroyed.
A window consists of several areas of slots with similar functionality - for example the crafting grid area, or
the inventory area. Each area knows what its slots are (GetSlot() function) and can handle mouse clicks.
The window acts only as a top-level container for those areas, redirecting the click events to the correct areas.
Inventory painting, introduced in 1.5, is handled by the window, too
