Comment 37 for bug 178558

"You cannot scale images except by 2, 4, etc."

That is not correct, as a simple look at The Gimp/Eye of Gnome/gThumb/etc. will show. You might make the argument that "you cannot scale images *quickly* except for integer scaling", but that is really not an issue save for very old machines (which are unlikely to be running high DPI displays) or for animated images (but there you can scale the individual frames once then just loop them).

It isn't even correct to say "Firefox lacks the ability to scale images by a non-integer amount", as it *HAS* to do that if an image's native size does not match what the HTML IMG tag specifies.
