Description

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.

Contributor guide

Research direction
Investigate how Fontconfig provides the pixelsizefixupfactor and implement upscaling for bitmap fonts in the FreeType backend when the factor > 1.
