Base class to derive custom decorator drawers from.
A DecoratorDrawer is similar to a PropertyDrawer, except that it doesn't draw a property but rather draws decorative elements based purely on the data it gets from its corresponding PropertyAttribute.
Unity uses builtin DecoratorDrawers for the SpaceAttribute and HeaderAttribute. You can also create your own DecoratorDrawers with matching PropertyAttributes.Although a DecoratorDrawer conceptually is not meant to be associated with a specific field, its attribute still needs to be placed above a field in the script. However, unlike PropertyDrawer attributes, there can be multiple DecoratorDrawers attributes above the same field. Also unlike PropertyDrawers, if a DecoratorDrawer attribute is placed above a field that is a List or an array, the decorator will only show up once before the array; not for every array element.| attribute | The PropertyAttribute for the decorator.
