[Feature Request] More scaling filters

[Comitant]

Overview

Include sharper scaling filters within the "Upscale" drop-down, such as bicubic catmull-rom or lanczos 2.

Smaller details

Currently, there's only nearest-neighbor, bilinear, and FSR 1.0 (which acts as an advanced lanczos 3) for image scaling. These are all good at achieving certain looks, but there's cases where someone might want sharper scaling without the artifacts that something like FSR 1.0 creates, and catmull-rom or lanczos 2 can achieve this goal.

Both catmull-rom and lanczos 2 are nearly identical, only one of which would be worth adding.

I can provide examples if needed.

Nature of request

More scaling filters

Why would this feature be useful?

These filters retain lots of detail and have good sharpness without being unnatural, as a result, it would improve overall image clarity, especially for downscaling.

Bicubic, lanczos 2 👍

Also add a tooltip that explains where each filters are best used (downscaling or upscaling, and general artstyle)

Or maybe even choose one filter for upscaling, one for downscaling, and then ryu choose the right one depending on the scenario.

So for example it use the upscaling one if your monitor is higher res than the game
and use the downsampling one if you play with ryujinx res scaler on a lower res monitor
(like on cemu)
and use nearest neighbor when integer scaling ?

Lanczos would be great
