    37      we want to handle clicks on the progress bar and convert those to seeks in the media.
       
    38      However, jquery only gives us a global position, and we want a number of pixels relative
       
    39      to our container div, so we get the parent position, and compute an offset to this position,
       
    40      and finally compute the progress ratio in the media.
       
    41      Finally we multiply this ratio with the duration to get the correct time
