If you need a local variable anyway - why not insted getting rid of
the boost::cref and pass the parameter by value in the first place?
e.g. , mpOwningSpriteCanvas->getBufferSurface(), _1 ... ?
Haven't tried, was looking for the minimal change to the existing
structure. One thing to keep in mind is that getBufferSurface() creates
a temporary variable. It doesn't return a reference itself.
