Used by the system (subclasses and hosts) to send the current data
value of this node to its receivers, without event processing and
regardless of event relaying.
Default implementation: Transforms intersector to the local space
using SwingSpaceMapper.INSTANCE, then calls this graphic's
Component.contains(x, y) method for the intersection test.
Called by the system to determine if some other state policy
is compatible with this one, such as when adding a state
value to a group of state values that should maintain a mutually
consistent state.
Returns true if this is a space transforming node (transforms its
local space, leaving its contents unchanged), and false if it is
content transforming (transforms its contents, leaving its local
space unchanged).
