bug#22951: 25.1.50; Visible bell too big on OSX

[sebastien]

Since commit bbe8a899ac91f93bcdb14fec8c200cd3f2256987 which increases 
the size of the icon 5 times, the visible bell has become way too big 
and distracting on the master branch: cf. attachments before.png vs. 
after.png on a full screen Emacs frame.


To reproduce:

emacs -Q -eval "(setq visible-bell t)"

and trigger bell by pressing up key until it reaches top of buffer.

Regards,
Sébastien.
