	Edge list is arranged as follows:

	all vertices are numbers between 0 and 24. x coordinate of vertex is vertex % 5,
	and y coordinate is vertex / 5.
	
	an edge is
		a direction code
		a number of vertices in the edge
		an array of vertices -- all vertices along the edge, whether or not they're
			clickable.
		an array of bools (bytes) indicating that a portion of the edge is
			traversed (and should be drawn). the number of bools is one less than
			the number of vertices.
	
	an edge list is
		an array of 25 bools indicating which vertex is clickable.
		an array of 25 bools indicating which vertex is used (drawn).
		a number of edges
		an array of edges.
	
	a hot vertex list is
