Bug#1032412: no message at dual screen

I have the same problem at dual screen with sizes 1280 x 1024 and 1280 x 
800.

New debian-logo tries to write the message "resuming from hibernation" 
below borh screens.

This is caused by wrong computation of max height.

In my case it computes 2 * 112 + 1024, which should be only 1024.

.Problem occurs at /usr/share/plymouth/themes/emerald/emerald.script.

Next patch solves the problem for me :diff --git
