public class MouseAppState
extends BasePickState

Keeps track of a set of "collision roots" for mouse picking and performs the pick event processing necessary to deliver MouseEvents and CollisionEvents to spatials with either the MouseEventControl or CursorEventControl attached. (The actual event delivery is done by the PickEventSession class for which this app state has one active session.)

PickEventSession behavior:

Collision roots may either be perspective or orthogonal and the appropriate type of collision is done. The ViewPort's camera is used to detect the difference.

Events are delivered in near to far order to any 'target' that the cursor ray collides with until the event is consumed. Enter and exit events are delivered as targets are acquired or lost.

If a button down event happens over a target then it is considered 'captured'. This spatial will be provided to subsequent events in addition to the normal target. Furthermore, any new motion events are always delivered to the captured spatial first.
