Allow to chain actions without intermediate images flickering on the screen

After updating pqiv my cycle keybindings that use send-keys (e.g. <space> { send_keys(:command); }) temporarily freeze pqiv and don't seem to do anything until subsequent keypresses (after which pqiv remains laggy).

My bad. Should be fixed in latest master?!

It's not freezing anymore, but my cycle keybindings aren't working as expected anymore. I have space send :cycleCN:

:cycleCN {
	set_shift_align_corner(CN);
	bind_key(h { goto_file_relative(-1\); send_keys(:cycleCS\); });
	bind_key(i { send_keys(:cycleCS\); });
}
:cycleCS {
	set_shift_align_corner(CS);
	bind_key(h { send_keys(:cycleCN\); });
	bind_key(i { goto_file_relative(1\); send_keys(:cycleCN\); });
}

I don't know if something else has changed. Hitting i for the first two times works as expected, but every subsequent press just aligns to the bottom and then immediately aligns to the top without going to the next image.

Wow, that's a pretty cool improvement on your initial version of those bindings :-)

This is an unrelated bug that had been there before but was shadowed by the issue I fixed in #119. I've updated master, please give it another try.

Thanks! It's working as expected now.

I don't remember this being the case before, or maybe I just noticed it now, but when going to the next image, I can see pqiv scroll the image up to the top (like a fast flicker). Is there or could there be some way to show the next image with an alignment set immediately? If this isn't simple to do, that's fine because this is a pretty minor issue.

I'll look into it, but don't expect anything too soon.. this'll require some rewiring regarding when actions are considered complete.
