Text is extra tricky here. Do you want zooming to show you more text, or
do you want it to make the font larger. Even if you choose to just make
the font larger the text object won't scale linearly with the
magnification, because of font hinting etc. I guess you could avoid this
by always rendering text unhinted, positioned using non-device
coordinates, but this will cause pretty unreadable text.
