Subject: imagebox: Don't try to scale by infinite (FS#1248)
X-Git-Url: http://git.naquadah.org/?p=awesome.git;a=commitdiff_plain;h=7967d05915c95c8eba7709a46093cc1b6de55572;hp=afa50904fb1c79a24ddda8fb242afe2dcc1de841
imagebox: Don't try to scale by infinite (FS#1248)
When an imagebox was drawn with width or height zero, it tried to calculate the
needed scale factor for making the image fit. Sadly, this would be a division by
zero aka infinite in this case.
Fix this by just not drawing anything if there is no space available.
