There are similar reasons re images from web content.
Firefox will scale, but will only render without interpolation if the web
content supports the resolution.

Windows usually scales in steps, 1, 1.25, 1.5, 2 (and maybe higher).
Adding a 1.5 step makes sense, I think, especially because this is supported
on Windows, and so has some chance of support from web authors.
I'm not so keen on adding 1.25 because the benefits of a different size don't
necessarily outweigh the disadvantage of likely interpolation. At 1.25, Windows defaults (in some versions at least) to XP scaling, which scales font sizes but not pixels. Doing this in web content broke too many sites.
The goal is to pick what will be best for most and layout.
