If there are no masks or mattes, the animation is drawn directly to the canvas and no bitmap allocations are necessary.

If there is a matte, an 8 bit bitmap will be created and if there is a mask, a 32 bit bitmap will be created and drawn to.

An animation can only be at one stage at a time but you can easily create multiple animations. If you want to have several copies of the same animation, there is a composition caching option that will prevent you from having to deserialize and parse the composition again.
