Detailed Description

template<class T = int, class Boolean = bool, class Float = double, class BoxType = AAArbitraryRectangle<T,Boolean,Float>>
class Boundary::BoundingEllipse< T, Boolean, Float, BoxType >

General-purpose ellipsoidal bounding box.

For simplicity, this is just a minor variation on AARBoundingBox, but if speed is important it can be made a fully-separate class instead so that it can cache the values of the parameters needed by inside().

To allow an arbitrary radius to be used even for an integer-bounded box, a "trim" value can be passed in; this will be added to the integer radius to get the floating-point radius. This somewhat- unorthodox implementation was chosen not because it's better than just using a floating-point radius in the first place, but because it made it easier to interface with older code structured in the same way.

Public Methods
	BoundingEllipse ()
	Default constructor: infinite extent.
	BoundingEllipse (T centerx, T centery, T radius, Float trim=0)
	Constructor for a circular area.
	BoundingEllipse (T centerx, T centery, T radiusx, T radiusy, Float trimx_i=0, Float trimy_i=0)
	Constructor for an ellipsoidal area.
virtual Boolean	inside (T x, T y) const
	Returns true if the given coordinates are inside the ellipse bounded by the corresponding rectangle.
virtual base &	rotate (Float theta)
	Rotate the box by the given angle (in radians).
virtual base *	clone () const
	Constructs an identical copy of self and returns it.
