What affects GPU mode rendering?

Hi all,

I use bitmap based rendering in GPU mode for performance. All vectors and fliters etc are converted to a bitmap at runtime. It's working great.

I understand that rotation and scale will not affect the performance - this is all handled by the GPU.

1) Does ColorTransform affect GPU (will the bitmap need to be rerendered and pushed into texture memory again?

2) What about masking the bitmap with a shape, or with another bitmap?

Cheers,

Peter
