// radius given), then for each object to test, calculate the distance to the 
// path and include it if the range fits and the target is in the line (0<k<1,
// as they call it).
// The implementation I took as reference is found at 
// http://astronomy.swin.edu.au/~pbourke/geometry/pointline/ 
// (they have a link to a C implementation, too)
// This approach is a lot like #2 commented on this function, which I have no 
// idea why it was commented. I won't use doubles/floats, but pure int math for speed purposes

/*
	Advanced Fusion Maps Support
	(c) 2003-2004, The Fusion Project
	- AlexKreuz

	The following code has been provided by me for eAthena
	under the GNU GPL.  It provides Advanced Fusion
	Map, the map format desgined by me for Fusion, support
	for the eAthena emulator.

	I understand that because it is under the GPL
	that other emulators may very well use this code in their
	GNU project as well.

	The AFM map format was not originally a part of the GNU
	GPL. It originated from scratch by my own hand.  I understand
	that distributing this code to read the AFM maps with eAthena
	causes the GPL to apply to this code.  But the actual AFM
	maps are STILL copyrighted to the Fusion Project.  By choosing

	In exchange for that 'act of faith' I ask for the following.

	A) Give credit where it is due.  If you use this code, do not
	   place your name on the changelog.  Credit should be given
	   to AlexKreuz.
	B) As an act of courtesy, ask me and let me know that you are putting
	   AFM support in your project.  You will have my blessings if you do.
	C) Use the code in its entirety INCLUDING the copyright message.
	   Although the code provided may now be GPL, the AFM maps are not
	   and so I ask you to display the copyright message on the STARTUP
	   SCREEN as I have done here. (refer to core.c)
	   "Advanced Fusion Maps (c) 2003-2004 The Fusion Project"

	Without this copyright, you are NOT entitled to bundle or distribute
	the AFM maps at all.  On top of that, your "support" for AFM maps
	becomes just as shady as your "support" for Gravity GRF files.

	The bottom line is this.  I know that there are those of you who
	would like to use this code but aren't going to want to provide the
	proper credit.  I know this because I speak frome experience.  If
	you are one of those people who is going to try to get around my
	requests, then save your breath because I don't want to hear it.

	I have zero faith in GPL and I know and accept that if you choose to
	not display the copyright for the AFMs then there is absolutely nothing
	I can do about it.  I am not about to start a legal battle over something
	this silly.

	Provide the proper credit because you believe in the GPL.  If you choose
	not to and would rather argue about it, consider the GPL failed.
