I've just added a brand new GUI example!

This time it's a wave player that draws the waveforms of the left and
right channels of the wave file, and also draws the playback position
as a typical sequencer would do.

It also allows you to change the playback position, just point and click!

Here's a screenshot (poor jpeg to save bandwidth): http://i.imgur.com/Wv5Lx.jpg

The drawing routine is a little bit expensive, this is due to drawing
a lot of lines with cairo in a single call. I'll have to investigate
how to make drawing faster.
