Comments matched to reassure the compiler that fallthrough is
intentional are supposed to precede the case or default keywords, at
least in GCC, so the one here did not suppress the warning with GCC. We
can just the if condition and put the comment at the end to solve that.

Add a --run option which takes the name of an example and
launches it. Also add a --autoquit option which can be used
to quit after a given number of seconds.
We really want margins around the scrollable content, not around
the viewport. Make it so by using textview-specific properties.
This is unfortunately a little complicated for top/bottom.
Loading a builder file with a window leaves a ghost behind, since
windows need to be explicitly destroyed. Avoid that by using
gtk_builder_add_objects_from_resource.
... for displaying resources. Instead use the proven and way more
reliable method of trial and error.
It's less code and more portable for a start.
But most of all it displays PNM files as text if you fail to compile
the gdk-pixbuf loader for it.
In commit 4e41577b, we are using g_content_type_is_a() to determine how
to display the demo resources in the right pane of the gtk3-demo program.
Use g_content_type_get_mime_type(), so that we can obtain the mime
type of the demo resources on all platforms, as g_content_type_guess()
returns a platform-specific string, as
https://developer.gnome.org/gio/2.35/gio-GContentType.html states.
As .ui files and .css files are normally registered with a different mime
type string on Windows, check for those strings as well.
This will ensure the demo resources can be properly displayed on Windows
as well.
This is so we can prepare these buffers without them being set on the
widgets yet and only gtk_text_view_set_buffer() them afterwards. And
this in turn gets rid of all the a11y events we were needlessly
emitting.

This way, people know what stuff we are loading.
And instead of listing all the files in the top (and forgetting things),
we just take them from the resources list.
