My initial analysis was done on a debug build (stupid!). In a release build,
things aren't nearly as bad. In the attached Shark profile of the testcase,
GraphicsContext::restore() is 1.4%, and GraphicsContext::save() 0.6%.

However, Font::operator= is still 39% of the time spent in
GraphicsContext::restore(), so I think there's still a win to be had here.
