Don't attempt to disable double buffering in newer GTK+ versions

Sigh, I had almost expected this would happen. Reverted with 2fa19cc551. But now we have another time bomb in the codebase: the gtk_widget_set_double_buffered function is deprecated and will probably be removed sometime. This makes the migration to a pure GTK+ build even more pressing.
