title: Drawing a path between two points
body: <p>I'm working on a touch based game, and I'm having issues drawing a path the user has touched through.
  I'm trying to mimic something like these apps <a href="http://www.youtube.com/watch?v=G3CECr6mT1Q" rel="noreferrer">http://www.youtube.com/watch?v=G3CECr6mT1Q</a> or <a href="http://www.youtube.com/watch?v=r34-_0wrVC4" rel="noreferrer">http://www.youtube.com/watch?v=r34-_0wrVC4</a></p>
  
  <p>I'm doing this in XNA/C#.</p>
  
  <p><strong>My issue is</strong>: I have the set of waypoints that define that users touch path. I wasnt sure how I could get a stylized line between all these points, so I thought "hey, I will just have a really small image that is 'the line', and draw it at every spot between the waypoints, and rotate it accordingly. I'm not sure this if this is the best solution or not.</p>
  
  <p>But I was stuck because I did not know how to get all the coordinates between these two points. I have the two points, I can get a vector from the first to second, etc, but I cant seem to get the math correct.</p>
  
  <p>Any suggestions or help?
  Thanks!</p>
