Added a link to the stable build

This algorithm is designed to find the distance of a certain region,
however it may have been better to do a quick check, rather than worrying
how many regions were loaded at once.

+	 * This algorithm is extremely complex and involed, but initial tests show
+	 * that it gives the right answers. The purpose is to determine how far off screen
+	 * a certain region is, so that it can be unloaded when necessary.
+	 * 
+	 * If the region is actually onscreen, then there's no reason to run the rest, so
+	 * the algorithm corrects for the camera's location, before checking the bounds of
+	 * the screen.
+	 * 
+	 * The next part is tricky. If X or Y is negative, then it is divided by the
+	 * graphical size of the regions, resulting in a usable integer, representing how
+	 * far from the screen it is in "region units". If, however, X or Y is larger than
+	 * 0, than first, the size of the screen is subtracted from that variable, before
+	 * it is then divided by the graphical size of a region. Finally, to compensate for
+	 * the off by one error, 1 is added at the end.
+	 *
+	 * Since only the magnitude of the distance in either direction is needed, this
+	 * method returns the largest absolute value of X or Y.
+	 * 
+	 * The final result of this algorithm is an integer representing how far, rounded
+	 * up, a certain region is from the screen's edges in any direction, measured in
+	 * "region units". This algorithm may be flawed, in which case, I recommend simply
+	 * replacing it with a boolean check, to see if the region's distance from the player
+	 * is larger than a certain value. This algorithm lacks the advantages I initially
+	 * expected, so that may be beneficial at some point.
