Jonas Dreßler 3eb40df06b panel: Don't change text color when entering the overview or lockscreen
With the introduction of the transparent panel in the overview, we
started making the panel text/icon color slightly brighter in the
overview and on the lockscreen to ensure best contrast. Now
unfortunately, setting the text color incurred a relayout of the
underlying ClutterText actor (fixed with
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1750), and
setting the icon color causes the icon texture to get regenerated
(fixed with
https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/932).
Regenerating the icon texture will replace the icon actor, which also
causes a relayout.

This relayout of the panel has been measured to add at least 1
millisecond (the numbers fluctuated a lot) to about 5 ms it takes to
layout the first frame when showing the overview.

Since https://gitlab.gnome.org/GNOME/gnome-shell/-/merge_requests/932 is
unlikely to land this cycle, this commit proposes a different solution:
Simply don't use a different color for text in the overview. To avoid
issues with contrast in the overview, make the default color slightly
brighter and change it from #ccc to #ddd.

Gnome-shell OSK layouts are extracted from CLDR layout definitions:
https://www.unicode.org/cldr/charts/latest/keyboards/layouts/index.html

Updating these involves several steps:

1) Downloading and unzipping the tarball found at:
   http://www.unicode.org/Public/cldr/latest/keyboards.zip

   This file contains XML files describing the keyboard layouts.

2) Cloning the cldr2json script at:
   git://repo.or.cz/cldr2json.git

   It will be used to convert the XML files into JSON that can be
   directly consumed by gnome-shell.

3) Running the script to produce the files:
   ./cldr2json <input-directory> <output-directory>

   We shall usually use the "android" folder, since that's most
   complete, and similar to our UI and target sizes. And the target
   directory must be data/osk-layouts in this repository.

4) Modify gnome-shell-osk-layouts.gresource.xml to include the files

5) Do git add on the updated/new files, and git commit.


Or alternatively:

1) Run update-osk-layouts.sh

2) Do git add and git commit
