Comment 3 for bug 140363

The likely problem here is that the 'font measure ...' returns a zero value for some unknown reason.
Since the iaxclient bug has been fixed after this bug was reported, there is a tiny probability
that it was the cause, but I don't think so. Why 'font measure ...' gives zero I have absolutely no idea.
With SVG we will switch from point to pixel font sizes why we don't rely on
some kind of add platform mapping.
