fontconfig before version 2.13.1 was apparently implicitly not using
subpixel antialiasing. The fontconfig NixOS module deviated from this,
using subpixel antialiasing with `rgb` layout by default. In fontconfig
2.14.1, subpixel antialiasing was inadvertently enabled as the default:
2b6afa02ab
According to https://gitlab.freedesktop.org/fontconfig/fontconfig/-/issues/337,
that deviates from GNOME/GTK’s defaults, which resulted in apps taking the
settings directly from fontconfig (e.g. Firefox) from diverging from GNOME
programs.
The change was subsequently reverted in 2.14.2, choosing the greyscale
antialiasing explicitly: 030759b74f
Let’s reflect this default setting in the NixOS module.
