commit b835bbd389017d87cc57fc1a2334c72a3a7a2364
Author: Robert Fewell <14uBobIT at gmail.com>
Date:   Fri May 1 11:58:00 2020 +0100

    Change occurrences of gdk_display_get_default
    
    It would be better to obtain the display from the current window
    instead of using the default one.

commit 3602753f5093313592dee6acf92b821fc604c976

    Remove some Gtk version checks in code
    
    With the requirement for Gtk+ 3.22, the version checks dealing with
    checking for version 3.20 or 3.22 are no longer required so these have
    been removed in the source files.

    Remove some Gtk version checks for CSS
    
    With the requirement for Gtk+ 3.22, the version checks dealing with CSS
    can be removed and the application CSS files dealing with version 3.10
    can be removed with the remaining being renamed.
