+/* 20191231 bkw: This seems like stupidity: g_content_type_is_mime_type
+   is a new function in glib-2.52, which literally just calls the
+   g_content_type_is_a function from older glibs, and returns its
+   result. Here's the function from the glib-2.52 source:
+
+   gboolean
+   g_content_type_is_mime_type (const gchar *type,
+                                const gchar *mime_type)
+   {
+     return g_content_type_is_a (type, mime_type);
+   }
+
+   The docs describe it as a "convenience wrapper" but there's
+   nothing more or less convenient about it, except that it breaks builds
+   with older glib versions. Why does it even exist?

+/* 20191231 bkw: We'd need gtk+-3.22 to have gtk_popover_popup and

+   Some folks might actually prefer it without the fade.
