Objects that implement this interface can be passed to the
LayoutManager's invalidateProperties() method.
When the LayoutManager reaches the commit properties phase,
the LayoutManager invokes this object's validateProperties()
method.
Similarly, if an object is passed to the LayoutManager's
invalidateSize() method, then the LayoutManager
calls that object's validateSize() method
during its measurement phase, and if an object is passed
to LayoutManager's invalidateDisplayList() method,
then the LayoutManager calls its validateDisplayList() method
during the layout phase.
The ILayoutManagerClient interface is implemented by the UIComponent and ProgrammaticSkin classes.

The top-level SystemManager has a nestLevel of 1.
Its immediate children (the top-level Application and any pop-up
windows) have a nestLevel of 2.
Their children have a nestLevel of 3, and so on.
The nestLevel is used to sort ILayoutManagerClients
during the measurement and layout phases.
During the commit phase, the LayoutManager commits properties on clients
in order of increasing nestLevel, so that an object's
children have already had their properties committed before Flex
commits properties on the object itself.
During the measurement phase, the LayoutManager measures clients
in order of decreasing nestLevel, so that an object's
children have already been measured before Flex measures
the object itself.
During the layout phase, the LayoutManager lays out clients
in order of increasing nestLevel, so that an object
has a chance to set the sizes of its children before the child
objects are asked to position and size their children.

Set to true after immediate or deferred child creation,
depending on which one happens. For a Container object, it is set
to true at the end of
the createComponentsFromDescriptors() method,
meaning after the Container object creates its children from its child descriptors.
For example, if an Accordion container uses deferred instantiation,
the processedDescriptors property for the second pane of
the Accordion container does not become true until after
the user navigates to that pane and the pane creates its children.
But, if the Accordion had set the creationPolicy property
to "all", the processedDescriptors property
for its second pane is set to true during application startup.
For classes that are not containers, which do not have descriptors,
it is set to true after the createChildren()
method creates any internal component children.
