I will try.

I don't understand how gpexecute.c and mouse.c work, but I see that
wx_gui.c does quite a lot with mouse.

There seems to be GetWheelAxis() in
http://docs.wxwidgets.org/trunk/classwx_mouse_event.html, but I'm not
sure how well that works if it works at all (no idea what happens in
case of diagonal movements). I don't find any zoom event in wxt
tutorial.

There is a documentation for Mac (NSEventTypeSwipe &
NSEventTypeMagnify working since 10.6):

https://developer.apple.com/library/mac/#documentation/Cocoa/Conceptual/EventOverview/HandlingTouchEvents/HandlingTouchEvents.html#//apple_ref/doc/uid/10000060i-CH13-SW10

but I have no idea yet where those events could be plugged it.

Yes, "u" works perfectly. The problem is that I was playing with
buttons in the window:
- replot
- apply previous zoom settings
- apply next zoom settings
- apply autoscale
None of them was able to reproduce the behaviour of "u". If I can use
mouse to change the range, I would find it useful to be able to use
the mouse to revert the change as well.

True. I'm not sure what is wrong with 2.9, but it might also be a bug
in their code, not just the need to rewrite the program. It would make
a lot of sense to resolve such bugs before 3.0 is released, but I
don't know how to create a minimal example to submit a bug report (if
there is one).
