[FEATURE] Nearest-neighbor scaling when zooming in

[zacholade]

Is your feature request related to a problem? Please describe.
When zooming in, it seems it scales pixels through bilinear interpolation. A setting to scale using nearest neighbor to avoid blurriness would be a great and useful feature for numerous applications!

Off the top of my head, pixel art comes to mind.
Furthermore, I work with brain scans as part of my thesis and it would be nice to zoom in on exact pixels without them getting contaminated from surrounding pixels. In particular I work with svgs.

Describe the solution you'd like
A clear and concise description of what you want to happen.
Implement a setting which enables nearest neighbor scaling when zooming in.
