This is also why when you scale up a CALayer its content its content looks interpolated - its the same number of pixels as before, just interpolated larger. If you exceed the maximum LOD of a tiled layer, you will see the same thing (which if you don't set a LOD bias means if you scale a tiled layer above 1.0 it will also have its content interpolated).
So why is it that when setting a CALayer's (not CATiledLayer) background color, corner and border properties, those render beautifully, no matter what the scale of the parent layer? Clearly, at some point, Quartz is getting called to fill & stroke the layer's frame with the appropriate CTM in place for it to appear as it does (scaled & rotated). I wish I could get it to do the same for my drawing code.
