The current SVG backend behaviour is due to the fact it is given only a
list on glyphs to display, without the original utf8 string. So emitting
a <text> element is not straightforward. We could probably do something
similar to what's done in the PDF backend, but that's not implemented

I don't remember exactly why I've added this clipping rectangle. I'll
try to have a look at this issue soon.
