Core Animation Caching Resolution

Hi,

I am having a CALayer with a scale-down transform and many sub layers. 
It seems to be the case that these sub layers cache their contents 
with 1 unit to 1 pixel, that is they ignore the (outer) transform 
until it comes to draw to the screen.

Is there a suggested way to work around this? What I want is to have 
the cache at screen resolution to keep memory usage controlled.

Thanks for any hints
Kai
