Thank you for the comments, I see here a few good points.
I have never realized that choosing "Auto" from the combo works the
same way as Home hot key. I am also interested if there are users who
use the combo box. I guess most people simply use the mousewheel or
hotkeys (correct me if I am wrong).
F1/F2 do not go throught the zoom list - they compute new zoom
settings basing on the current one. GAL sometimes uses non-standard
zoom values. I do not know if you noticed, but if you zoom using mouse
wheel, the zoom changes depend on the scrolling speed (to be precise -
intervals between consecutive scroll events).

I am wondering - is the step 4 really necessary? The current scrolling
behaviour does not warp the mouse cursor (as advised in UI handbooks)
and still zooms in the object under the cursor. Does it matter if it
is perfectly in the screen center or offsetted a bit?

Jumpy scrolling requires to warp the mouse cursor, I am trying to
avoid it as much as possible.
It should not be very hard to adjust border panning speed in the code,
but there is still no option UI to do so. It would be better not to
add GAL-specific settings now, as they may confuse users if they do
not apply to the default renderer.

I am wondering if the Cairo backend would not work better for you.
Long time ago I was experimenting to enhance the performance . To
gain even more speed, you could also disable antialiasing as I know
you hate it.
