68ac6486b1 Fix alpha blending
- "/ 257", because 255 * 257 = UINT16_MAX
- "/ 255", because that's the maximum possible RGB value

022ae48360 Change an eprintf to a die to stop child from running its own slideshow
The child thread was created because execlp will not return if successful.
The eprintf was placed after the call to execlp to catch any error, but the
child continued to return a (closed) fds[0], resulting in a second slideshow
being run by the child.

This commit fixes the issue by killing the child.

b516f468fa Support farbfeld as an intermediate format
Sent now uses farbfeld[0] as an intermediate format.  A series of
filters is specified in config.h that matches file extensions to
filter programs.  The programs will convert between formats such as
png to farbfeld.  Internally in sent we do not need to worry on how
to parse png or any other format.

This also works with jpg and gif and others.  The 2ff wrapper will
use imagemagick conversion tools.  This is temporary as jpg2ff and
gif2ff will also be implemented.

To make this work, you will have to clone[0] and put png2ff and 2ff
in your PATH.

a1dcdad14f Bail out before allocating slides if file is empty
In load() we allocated slides before checking if we actually read
anything from the FILE fp and then continue with an allocated but
“empty” space wich would lead to errors.

4a828c2d6c prevent flickering when changing slides
When the window background is left at WhitePixel (from initialization) and the
user has set a dark background color in config.h, the window shortly displays
the white default background when clearing after advancing to another slide.
This was very disturbing and is fixed now by setting the default window
background color to the bgcol chosen in config.h.

8b52c85dd1 don't assume we get a ConfigureNotify event
If the window manager maps our window at the requested size, we may not get a
ConfigureNotify event.  This happens e.g. under ratpoison.

The result is that xw.uw and xw.uh are never set, so text is too small and
pngscale() tries to divide by 0.
