 If you generate a wave with showwave filter set to mode=point, you can get
 a result which is almost invisible because of high resolution (points are
 too far from each other).

 I suggest to add new mode=p2p which draws a line between those points and
 makes output more readable.

 I tried to do it on my own and here is the result:

 Example 1 - http://www.datafilehost.com/d/5b822974 (mode=point on top,
 mode=p2p on bottom)
 Example 2 - http://www.datafilehost.com/d/f0457d43 (mode=p2p standalone)
 Patch: http://www.datafilehost.com/d/af6aafad

 It's not perfect but it seems better to me. I would be glad if anyone can
 look at it or even improve it.

 Thank you for any reply.
