0.99.7: Zoom-out does not actually use the resizing algorithm chosen

[fireattack]

1. Go settings -> View -> High zoom quality: Zoom-out and Zoom-in, and choose one of the algorithm in the following drop down menu
2. Open a large image and zoom out (or just fit to window).
3. Change the algorithm.

Comparing two very different algorithms is prefered, like bilinear vs. lanczos4.

You can screenshot at step 2 and 3 and compare them pixel by pixel. There is literally no difference.

This bug does not happen if you zoom-in (enlarge); the algorithm actually makes a difference.

zoom is > 100%?

[fireattack]

no, zoom is < 100%.

Bilinear:

Spline36:

No difference whatsoever.

[xnview]

for zoom < 100%, bilinear is always used

[fireattack]

for zoom < 100%, bilinear is always used

Well, the option says "high quality for zoom-in and -out" which I thought would include zoom <100%.

High(er) quality downscaling (mainly, sharper) is something I would like to have.
