Improve preview quality when dragging / zooming

[Michael Ezra]

When zoomed in, the moment user clicks the preview with the Hand tool or zoomes in, the preview first becomes pixelated, and only after that gets rendered into its final high quality state.

This is I think a result of the technical debt and is not the feature that is user-friendly.

1. In the short term, would it be possible, to avoid such pixelisation while dragging and zooming?
2. Ultimately, if this can become fluid this would significantly improve the feel of the software.

I agree this is a good suggestion, but it might need quite some work to implement. ART (like RT) tries to always process only what is currently visible, and this would need to change in order to implement high-quality dragging/zooming. Certainly doable, but not just a couple of hours work…
