		<div>
		box -- Box that will be unioned with this box.
		</div>
		<div>
		Unions this box with *box* setting the upper bound of this box to the greater of the
		two boxes' upper bounds and the lower bound of this box to the lesser of the two boxes'
		lower bounds.
		</div>

		<h3>[method:Vector2 getParameter]( [page:Vector2 point], [page:Vector2 optionalTarget] ) [page:Box2 this]</h3>
		<div>
		point -- [page:Vector2]<br/>

		<h3>[method:Box2 expandByScalar]( [page:float scalar] ) [page:Box2 this]</h3>
		<div>
		scalar -- Distance to expand.
		</div>
		<div>
		Expands each dimension of the box by *scalar*. If negative, the dimensions of the box </br>
		will be contracted.
		</div>

		<h3>[method:Box2 intersect]( [page:Box2 box] ) [page:Box2 this]</h3>
		<div>
		box -- Box to intersect with.
		</div>
		<div>
		Returns the intersection of this and *box*, setting the upper bound of this box to the lesser </br>
		of the two boxes' upper bounds and the lower bound of this box to the greater of the two boxes' </br>
		lower bounds.
		</div>

		<h3>[method:Boolean containsBox]( [page:Box2 box] ) [page:Box2 this]</h3>
		<div>
		box -- Box to test for inclusion.
		</div>
		<div>

		*offset* units in 2D space.
		</div>

		<h3>[method:Boolean isEmpty]() [page:Box2 this]</h3>
		<div>
		Returns true if this box includes zero points within its bounds.</br>

		<div>
		point -- Point to measure distance to.
		</div>
		<div>
		Returns the distance from any edge of this box to the specified point. </br>
