Fractional scaling patches should be applied to gnome-control-center

[pshirshov]

Currently Gnome on Nix doesn't support fractional scaling under X11, which makes life utterly inconvenient.

Just two simple patches can fix that:

• https://salsa.debian.org/gnome-team/gnome-control-center/-/raw/ubuntu/master/debian/patches/ubuntu/display-Support-UI-scaled-logical-monitor-mode.patch
• https://salsa.debian.org/gnome-team/gnome-control-center/-/raw/ubuntu/master/debian/patches/ubuntu/display-Allow-fractional-scaling-to-be-enabled.patch

It would be good to have them at least as an option.

Well, seems like just these two patches are not enough. This code falls to the end while it should stop on xrandr branch.

+get_fractional_scaling_key (CcDisplayConfig *self)
+{
+  const char *renderer = cc_display_config_get_renderer (self);
+
+  if (!renderer)
+    g_return_val_if_reached (MUTTER_FEATURE_FRACTIONAL_SCALING_WAYLAND);
+
+  if (g_str_equal (renderer, "xrandr"))
+    return MUTTER_FEATURE_FRACTIONAL_SCALING_X11;
+
+  if (g_str_equal (renderer, "native") || g_str_equal (renderer, "kms"))
+    return MUTTER_FEATURE_FRACTIONAL_SCALING_WAYLAND;
+
+  g_return_val_if_reached (NULL);
+}
+

The P/R is ready and everything works fine: #137556
