Description Jens Ramke 2020-08-14 11:18:47 UTC 
Currently, automatic zoom in "Fit to window" mode is limited to image size shrinking.
I would like to request the option to enable image size increasing to fit to window as well.

Additionally, options to select the resizing algorithm would be nice.
I'd recommend at least Nearest Neighbor, Bilinear, Bicubic and Lanczos.
Ideally, this option would be settable independently for both decreasing and increasing of image size.
If you want to get fancy, there could be an option to automatically use nearest neighbor, maybe with added texel borders, with higher zoom levels.
