	< Answer whether the receiver is above and to the left of aPoint.
	<= Answer whether the receiver is neither below nor to the right of aPoint.
	= Answer whether the receiver and the argument represent the same object. If = is redefined in any subclass, consider also redefining the message hash.
	> Answer whether the receiver is below and to the right of aPoint.
	>= Answer whether the receiver is neither above nor to the left of aPoint.
	hash Hash is reimplemented because = is implemented.

	asPoint Answer the receiver itself.
	corner: Answer a Rectangle whose origin is the receiver and whose corner is aPoint. This is one of the infix ways of expressing the creation of a rectangle.
	extent: Answer a Rectangle whose origin is the receiver and whose extent is aPoint. This is one of the infix ways of expressing the creation of a rectangle.
	isPoint Overridden to return true in Point.
	rect: Answer a Rectangle that encompasses the receiver and aPoint. This is the most general infix way to create a rectangle.

	copying	top
	deepCopy Implemented here for better performance.
	veryDeepCopyWith: Return self. I am immutable in the Morphic world. Do not record me.

	geometry	top
	isInsideCircle:with:with: Returns TRUE if self is inside the circle defined by the points a, b, c. See Guibas and Stolfi (1985) p.107
	sideOf: Returns #left, #right or #center if the otherPoint lies to the left, right or on the line given by the vector from 0@0 to self
	to:intersects:to: Returns true if the linesegment from start1 (=self) to end1 intersects with the segment from start2 to end2, otherwise false.
	to:sideOf: Returns #left, #right, #center if the otherPoint lies to the left, right or on the line given by the vector from self to end
	triangleArea:with: Returns twice the area of the oriented triangle (a, b, c), i.e., the area is positive if the triangle is oriented counterclockwise

	interpolating	top
	interpolateTo:at: Interpolate between the instance and end after the specified amount has been done (0 - 1).

	point functions	top
	bearingToPoint: Return the bearing, in degrees, from the receiver to anotherPoint. Adapted from Playground, where the ultimate provenance of the algorithm was a wild earlier method of Jay Fenton's which I never checked carefully, but the thing has always seemed to work
	crossProduct: Answer a number that is the cross product of the receiver and the argument, aPoint.
	dist: Answer the distance between aPoint and the receiver.
	dotProduct: Answer a number that is the dot product of the receiver and the argument, aPoint. That is, the two points are multipled and the coordinates of the result summed.
	eightNeighbors
	flipBy:centerAt: Answer a Point which is flipped according to the direction about the point c. Direction must be #vertical or #horizontal.
	fourNeighbors
	grid: Answer a Point to the nearest rounded grid modules specified by aPoint.
	insideTriangle:with:with: Return true if the receiver is within the triangle defined by the three coordinates. Note: This method computes the barycentric coordinates for the receiver and tests those coordinates.
	nearestPointAlongLineFrom:to: Note this will give points beyond the endpoints. Streamlined by Gerardo Richarte 11/3/97
	nearestPointOnLineFrom:to: This will not give points beyond the endpoints
	normal Answer a Point representing the unit vector rotated 90 deg clockwise.
	normalized Optimized for speed -- ar 8/26/2001
	octantOf: Return 1..8 indicating relative direction to otherPoint. 1=ESE, 2=SSE, ... etc. clockwise to 8=ENE
	onLineFrom:to:
	onLineFrom:to:within: Answer true if the receiver lies on the given line segment between p1 and p2 within a small epsilon.
	quadrantOf: Return 1..4 indicating relative direction to otherPoint. 1 is downRight, 2=downLeft, 3=upLeft, 4=upRight
	rotateBy:centerAt: Answer a Point which is rotated according to direction, about the point c. Direction must be one of #right (CW), #left (CCW) or #pi (180 degrees).
	sortsBefore: Return true if the receiver sorts before the other point
	squaredDistanceTo: Answer the distance between aPoint and the receiver.
