GtkStyleContext will be deprecated in gtk 4.10.
https://docs.gtk.org/gtk4/class.StyleContext.html
This preserves code blocks where additional GtkStyleContext operations
were used, such as gtk_style_context_save/restore.
While it isn't possible, or even advisable, to make all the list
box rows the same height, using a number of standard heights will
make the control center feel more harmoneous.
Adust the height of the list box rows in Color, Date & Time,
Mouse & Touchpad, Network, Privacy, Region & Language, Sharing
and Universal Access. Makes standard rows that contain labels
and/or controls 58px tall. Some other rows, such as those which
contain two lines of text, are allowed to be taller.

This matches the new mockups as specified by Allan in
https://raw.github.com/gnome-design-team/gnome-mockups/master/system-settings/color/panel.png
The CcColorDevice and CcColorProfile widgets are lines in the EggListBox and are
smart by watching for changes in each colord device.
To use this new functionality you need colord from git master, and for the
'Laptop' devices to be recognised as internal, you also need to be _running_
gnome-settings-daemon from git, although this is not strictly required.
