Scene Graph Functionality.
void	add_child (node *child)
	Add a child node. Also sets the child's parent to `this`.
bool	connect (node *branch)
	If this is called on the root of a scene graph, it will insert the branch node in the appropriate place in the graph, or return false.
void	detach ()
	Removes the node from the scene graph (does not delete it!).

static void	draw_scene (gsgl::scenegraph::context *c, pre_draw_rec &rec)
	Draws a scene. Safe to call while update is also being called in the tree.
static void	pre_draw_scene (gsgl::scenegraph::context *c, pre_draw_rec &rec)

virtual gsgl::real_t	get_priority (gsgl::scenegraph::context *)
	Called to determine the draw priority of the node.

gsgl::real_t get_priority ( gsgl::scenegraph::context * ) [virtual, inherited]

Called to determine the draw priority of the node.

A value of NODE_DRAW_IGNORE means don't draw (invisible nodes or nodes that are drawn by their parents -- the modelview matrix is still built). A value of NODE_DRAW_SOLID means the object is solid and should be drawn after the painter's algorithm. A value of NODE_DRAW_TRANSLUCENT means the object is translucent and should be drawn after solid objects. A value > NODE_DRAW_TRANSLUCENT is interpreted as the distance to the object. Objects that return > 2.0 are drawn with a painter's algorithm.

Reimplemented in vehicle, submesh_node, test_frame, checkered_box, celestial_body, galaxy, large_lithosphere, large_rocky_body, planet_system, solar_system, and stellar_db.
