Misplaced UI element anchor gizmos if parent is a child of LayoutGroup

[jpauloruschel]

Description

Anchor gizmos for UI elements are using width and height, which leads to misplaced anchor representation and editing if the element is actually a child element of a layout. In that case, it should use calculatedWidth and calculatedHeight instead.

See image below: the anchor is set to [0, 0, 1, 1] (meaning bottom-left and top-right), but the gizmos are misplaced.

Steps to Reproduce

1. Create Element with LayoutGroup and fitting enabled
2. Create a child Element with LayoutChild
3. Create yet another child (below entity from point 2, making it a grand-child of the LayoutGroup). The anchor gizmos of this entity will not be correctly placed.
