this does not need to be a fatal error.
if im is NULL we're going to load it with imlib2 anyways.
one other problem this solves is that before, due to the fatal error,
the tmpfile opened under /tmp wouldn't get cleaned up.
Closes: https://github.com/nsxiv/nsxiv/issues/69
* set bar and text colors independently
* change xresources to Program.class.resource
* rename color variables to win/bar_bg/fg
* change default bar colors to match window colors
Since d8114e8 the file name is used for caching as-is without adding
.jpg at the end, but sxiv -c still expected old format causing it to
remove all fresh thumbnails.
Fixes issue #295
The imlib2 TGA loader returns an imlib image handle without any actual data
when given a text file like this:

Fortunately, `imlib_image_get_data()` returns NULL in this case, so that we can
use it as an additional check when opening files.
- Functions warn() and die() replaced by GNU-like error(3) function
- Register cleanup() with atexit(3)
- Functions called by cleanup() are marked with CLEANUP and are not allowed to
call exit(3)
- Only load the thumbnails that are currently visible in the window
- Unload thumbnails that are leaving the visible area
- Much less memory needed, but scrolling is now slower
- This also unintentionally fixes issue #86
The function "free" performs input parameter validation.

It is therefore not needed to check a passed pointer before this function call.
A corresponding update suggestion was generated by the software "Coccinelle"
