If you have a mouse-wheel, the "zoom using the mouse wheel" (or
two-finger scroll, or whatever on a touchpad) is the more convenient
way to zoom, if you haven't noticed already. Sure, the way we move
around the zoom is a bit odd (we move around so that the mouse pointer
is basically always over the exact same spot as in the non-zoomed
view), but I think it's something you get used to.

That said, if somebody more gtk-knowledgeable would want to turn the
zoom into a more traditional "use mouse-drag and/or scrollbars to move
around", I wouldn't object. I'll happily admit that the only *real*
reason for the odd "zoom moves with mouse" is that I could implement
that with no gtk knowledge at all, and just a bit of clever cairo
scaling/translation.
