// Methodology:
// My trigonometrics and math are a little rusty... so the approach I am writing
// here is basicly do a double for to check for all targets in the square that
// contains the initial and final positions (area range increased to match the
// 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. The range considered is always the same no matter how
// close/far the target is because that's how SharpShooting works currently in
