I asked about that before and never got any response. It would seem to 
me that scaling by an integer is not only sharper but may be faster on 
some hardware.

Conversely it seems doubtful any client really wants their fullscreen 
app to be scaled 1:1 and in a box in the middle, unless this is just the 
only way to get it fast. And this one is easily done by using a 
subwindow and it is hard to imagine any hardware acceleration that 
solution would bypass.

So it seems like the options should be "as large as possible" and "as 
fast as possible". The fast one may do something like "the largest 
integer scale that fits on the screen". Or if scaling fast is impossible 
it will do 1:1 centered.
