描述

Fontconfig provides us with fixup factor that we should use to scale bitmap fonts. Currently alacritty can only perform downsampling, however it'll be nice to have upscaling for bitmap fonts, since they often has pixelsizefixupfactor more than 1.

研究方向
The issue requests implementing upscaling for bitmap fonts using the fixup factor provided by Fontconfig. The relevant code is likely in the FreeType/Fontconfig backend, possibly in files like `src/font/ft.rs` or similar. The discussion may need to explore how `pixelsizefixupfactor` is currently used and where downsampling is implemented. The single comment (if any) or the issue itself does not provide further direction, so investigation into the font scaling algorithm is needed.
