 'fastiv' is a fast image viewer, supporting BMP, PNG, GIF, JPEG, and optionally
 RAW pictures.

+It is meant to be a viable replacement for Eye of GNOME, which is slow, likes
+to break on huge pictures, and its underlying gdk-pixbuf can only be made to use
+the broken libopenraw
+https://mail.gnome.org/archives/eog-list/2016-January/msg00004.html[as of now].
+
+Further development
+-------------------
+Urgent blockers for the first stable version:
+
+ - directory browsing
+ - implement zoom and scrolling
+
+High priority:
+
+ - some level of asynchronous loading and preloading,
+   which becomes a difficult problem with network mounts,
+   confusingly acting as fast devices
+ - write a replacement for GNOME's Nautilus in grid mode:
+   read-only, with focus on staggered previews and minimising wasted space
+
+Low priority:
+
+ - display 16-bit pictures smoothly, using the 30-bit depth under X.org
+ - make RAW as fast as it can possibly be
+ - load everything that resembles a picture, potentially even play video
+
+Non-goals:
+
+ - fancy UI, focus solely on speed of use
+ - memory efficiency, though preloading can cause some pressure
