[maemo-community] Zoom In/Out with a single Finger

[From: Joaquim Rocha]

Hi,

I kinda implemented something like this for the Maemo port of the Eye of
GNOME.

What I did was, if you tap twice and the second time you touch the
screen, you can drag your finger to zoom the image. Dragging to the
right (or diagonal right) will increase the zoom, dragging to the left
will decrease it.

You can check the EOG code here, look for src/eog-scroll-view.c (don't
forget it's on the "mobile" branch):
http://git.igalia.com/cgi-bin/gitweb.cgi?p=eog.git;a=summary

and you can watch a video of EOG here: (the zoom with one finger is done
at 00:50):

Hope it helps.
