 // Mac Backing Stores:
 //
 // Since backing stores are only ever written to or drawn into windows, we keep
 // our backing store in a CGLayer that can get cached in GPU memory.  This
 // allows acclerated drawing into the layer and lets scrolling and such happen
 // all or mostly on the GPU, which is good for performance.
