Yes I understand this.

IMHO this design is incorrect however. A client cannot take full 
advantage of all possible surface sizes because they must be multiples 
of the buffer scale.

In any case this really is a problem with the buffer_scale api. I think 
it will be fixed once somebody tries to write a serious application that 
takes advantage of a hi-res screen.
