[Bug 2258723] New: Variable fonts packages dont include all axis

https://bugzilla.redhat.com/show_bug.cgi?id=2258723

Bug ID: 2258723
           Summary: Variable fonts packages dont include all axis
           Product: Fedora
           Version: 39
                OS: Linux
            Status: NEW
         Component: google-noto-fonts
          Keywords: RFE
          Severity: low

  Target Milestone: ---
    Classification: Fedora

The *-vf packages package files from the `slim-variable-ttf` dir, which do not
include every axis available for the font. Variable font files with all
supported axis are in `variable-ttf` dir instead.

Reproducible: Always

Steps to Reproduce:
1. Install `google-noto-sans-vf`
2. Check which axis are supported
3. Download
`https://github.com/notofonts/notofonts.github.io/archive/refs/tags/noto-mont...
and look in the `fonts/NotoSans/unhinted/variable-ttf` direcotry
Actual Results:  
Only the weight axis is variable in this package

Expected Results:  
The weight and width axis are variable in this package

Changing the path at
https://src.fedoraproject.org/rpms/google-noto-fonts/blob/rawhide/f/google-n...
works for every variable font/script except for NotoKufiArabic, which has the
complete font files in the `variable` dir.

Before compression, this is ~16mb larger than before (total, across all
subpackages).

--- Comment #1 from vtq  ---
The included weight in the `slim-variable-ttf` font files of Noto Sans and Noto
Serif also seems to be limited to only 400 to 700.

"""
Well, we can't simply go ahead with this change. There are a known problem in
fontconfig about a sort of rounding error for width constant. wdth axis may not
work as expected.
