AffineTransform tweaks, any?

The AffineTransform functionality set is just outstanding, both in features and quality. I really enjoy using it. Thank you.

Question: Is there a way to affect the quality (or performance) of for example scaling? I'm quite happy with both quality and performance (I'm scaling up to zoom in) but I'm obviously getting an appropriate blurring. I am imagining there could (?) be a way to sharpen the upscaling.
