Debugged this today thoroughly. It seems I am getting repeated draw
signals from GTK. i.e. my expose method is being called repeatedly by
GTK. I am not constantly queuing draw calls as first suspected. Will try
to initially fix this from the GTK side, if all else fails I will try to
attempt to ignore the irrelevant expose calls.
When there is album art expose is called excessively too but I
filter/ignore a large set of these by comparing the album art path with
what is current on display.
When there is no album art everytime a new image is prepared using pango =>
expensive.
