Well on the background thing... I have no idea how to move it... But it 
is somewhat of the size that would be needed now I guess. But the other 
option of just coloring the Clef seems easier as far as I can see, if 
you need to used coordinate every single time to move it on the paper.

Is there a way to make a color glow from an image? :) I actually need 
something of that sort for the colored notes.
