Well, the preset steps are there for a reason: I touched that code some
years ago and it was quite a bit of back and forth until we settled on
the current solution.

The steps are based on sqrt(2) factors inbetween, tweaked heavily
towards "nice" ratios (e.g. 141% --> 3:2). It might sound stupid, but
these "nice" ratios are important for users: They have a predictable
and even distribution of the pixels. Hence a global percentage step was
not satisfactory at this time.

I don't see the zoom steps going away. However, adding a new zoom method
that allows for a smoother zoom for e.g. the mouse wheel shouldn't be
too hard.
