bug#22746: 25.0.90; OS X: Visual bell hard to see

[Adrian Robert]

The visual bell on OS X used to be a large square popped up in the middle of
the screen, which was easy to see.  Now it is a very small warning icon, and I
often miss it.  Would it be possible to make the warning icon the same size as
the square was, or if the icon can only be rendered at that size, provide an
option for the old square?
