| rect | Rect to be modified and centered. |
Modifies the input rect so it is centered and have a height equal to EditorGUIUtility.singleLineHeight.
This method can be used in RowGUI for centering and adjusting the row rect using EditorGUIUtility.singleLineHeight. In general it is a good idea to use a rect with EditorGUIUtility.singleLineHeight for labels and controls if working with row heights larger than the default row height.
