Get the height used for a single Editor control such as a one-line EditorGUI.TextField or EditorGUI.Popup.

When creating your own multi-line controls, such as controls for custom classes with multiple fields, you can use EditorGULayout.GetControlRect and pass in a height value that is a multiple of EditorGUIUtility.singleLineHeight. This is advisable over hardcoding specific pixel values. See Also: EditorGUILayout.GetControlRect.
