From 5e75b5ef3e7d0270913c04645398bc3596c2a90a Mon Sep 17 00:00:00 2001
From: Daniel Friesel <derf@finalrewind.org>
Date: Wed, 14 Feb 2018 22:33:38 +0100
Subject: Only check image dimensions on the fly in multiwindow and slideshow
 mode

This introduces a new feh_should_ignore_image function which is called
at appropriate places in those modes to skip images which are loadable but
undesired.
