OnRelayout(Vector2, RelayoutContainer)

Called after the size negotiation has been finished for this control.
The control is expected to assign this given size to itself or its children.
Should be overridden by derived classes if they need to layout views differently after certain operations like add or remove views, resize, or after changing specific properties.
As this function is called from inside the size negotiation algorithm, you cannot call RequestRelayout (the call would just be ignored).

Declaration
public override void OnRelayout(Vector2 size, RelayoutContainer container)
Parameters
Type Name Description
Vector2 size

The allocated size.
RelayoutContainer container

The control should add views to this container that it is not able to allocate a size for.
