// Description : The "top" node of the new Panda GUI system. This
|
|
// node must be parented to the 2-d scene graph, and all
|
|
// PG objects should be parented to this node or
|
|
// somewhere below it. PG objects not parented within
|
|
// this hierarchy will not be clickable.
|
|
//
|
|
// This node begins the special traversal of the PG
|
|
// objects that registers each node within the
|
|
// MouseWatcher and forces everything to render in a
|
|
// depth-first, left-to-right order, appropriate for 2-d
|
|
// objects.
