GUILayoutBeginArea

GUILayoutBeginArea is a Unity Editor script function used to define a rectangular area within the Editor's GUI where subsequent Editor GUI elements will be rendered. This function is part of the `UnityEditor` namespace and is typically used within custom editor windows or inspector scripts to organize and group GUI controls.

The function takes two arguments: a `Rect` struct defining the position and size of the area, and an optional string label that can be displayed as a title for the area. All GUI elements created after calling `GUILayoutBeginArea` and before calling `GUILayoutEndArea` will be contained within the specified rectangle. This allows developers to create distinct sections within their editor interfaces, controlling their layout and appearance independently.

For example, one might use `GUILayoutBeginArea` to create a collapsible section, a tabbed interface, or simply to visually separate different sets of controls. The `Rect` can be defined using absolute pixel coordinates or relative to the parent container. This provides flexibility in designing complex and user-friendly editor tools. When using `GUILayoutBeginArea`, it is crucial to always pair it with a corresponding `GUILayoutEndArea` call to properly close the defined GUI area and ensure subsequent GUI elements render correctly outside of it.
