I usually create the layers (if there's a fixed number of them) in the

backingScaleFactor).
Is this strategy documented somewhere? The High-Resolution Guide says to
avoid looking at the windows backingScaleFactor at all, but it's very sparse
on details about supporting CALayer.
https://developer.apple.com/library/mac/#documentation/GraphicsAnimation/Conceptual/HighResolutionOSX/Introduction/Introduction.html
talks a little about layers but is rather unclear on how and when to initalize a
layer contentScale properly. I don't recall reading about avoiding
backingScaleFactor, though.
