iPhone Slow canvas refresh

[Fojam]

I implimented icl's zoom feature into my game. When i put it on my 4th gen ipod, the canvas refresh is incredibly choppy and slow.
Is there any way to fix this?

Currently canvas is pretty slow on mobile devices, and I'd suggest avoiding it. 1.5 may bring increased speed for things like this, as well as dealing with transparency, but for now heavy canvas work on idevices is known to slow down the game, and can't be avoided.
