The implementation looks very similar to what Balázs did back in 2010 to 
the Docking Bar[1], even though his changes never made it into the Trunk.
One main difference I see is that he used a single "pragma", instead of 
two separate "pragmas". Performance-wise a single "pragma" is better. Is 
there any advantage of using two "pragmas", instead of one?
