Even though System.Windows.Point does contain the strongly-typed function...

        public bool Equals(Point value)
            return Equals(this, value);

...this overload will normally not be called (i.e. by EqualityComparer<Point>.Default), because the Point structure does not mention IEquatable<Point> in its declaration.

Instead, the non-strongly-typed Equals(Object) overload is called. It seems to me that this will have a constant performance penalty of boxing the value-typed argument every time.
