Refresh current picture through a Signal

[karatedog]

In a non-slideshow mode SIGUSR1 or SIGUSR2 could be reused for refreshing the current picture. Now it just simply exits feh..
I use feh as a permanent image display for my projects where the results are bitmaps and I don't want to fiddle with console to run feh.
Now I use the -R parameter but it would be much nicer just to send a signal when my application has just finished modifying the image -> this would help overcome that the -R parameter only accepts integers.

I've started implementing it, but it's not yet perfect (seems to miss the reload on the first signal). I'll fix that later on, it'll definitely be included in the next release.

Thanks :-) I'm looking forward to it.

Is this feature still working? I'm testing, but it does not look to work properly.

P.S.: I got it. The default mode is slideshow, hence it's needed to set up a different mode for the feature to work. Since I'm only using one window, I am using --multiwindow tag to activate the feature without problems. I think this comment might help someone in the future. =)
