[PATCH] shell: support zooming without a pointer device

[Stanislav Vorobiov]

This patch fixes weston crash when zooming using "super + pgup/pgdn"
binding on systems without a pointer device (i.e. touchscreen only)
Please apply http://lists.freedesktop.org/archives/wayland-devel/2014-May/014576.html
first before trying this one out.

Also, systems without a pointer device experience other crashes,
e.g. when using "drag and drop" or exposay, IMHO it makes sense
to fix those as well with separate patches...
