I've only just switched to living in MacOS X, so this is bugging me on 
a daily basis too. As I remember from the time I looked at this, the 
problem is that the bounds we're passing to DrawThemeButton is the 
clipped boundary of the button -- it's actually drawing outside those 
bounds, and so we have to compensate for that by reducing the requested 
bounds. It was worse in 10.1 when there was even more significant stuff 
outside the bounds proper.

I don't have a proper solution right now -- we're already doing the 
wrong thing by mucking with the bounds by 3 pixels on each edge when 
its for a default button because the old appearance manager wouldn't 
take the default ring into account regardless of the settings of the 
ThemeButtonDrawInfo struct we pass in to GetThemeButtonContentBounds.
