From 89bcb2dbe5b5e6eb8e8ba13ceecee2770dfe4cd4 Mon Sep 17 00:00:00 2001
From: Zero~Informatique
Date: Thu, 9 Jan 2020 02:10:35 +0100
Subject: viewer: Changed "image" type to "picture". Adapted the code to the
 current compiler output format. The currentItem and currentPath are
 calculated in the store for easier multi-component access. Breadcrumb for
 current's position and navigation.
