Patch: implement pointer axis events using GDK smooth scroll events

Add implementation of wl_pointer_listener pointer axis events. For this, we convert the events to GDK smooth scroll events, so we may accept any value in the event, even when at least weston x11 still only sends standard -1/+1 values.

Adding Rob Bradford to Cc:, as he's done the merge of the new 0.9x wayland GDK backend implementation.

Hi,

I submitted some patches[0][1] to wayland-devel related to this patch. Looking at the implementation in GDK/GTK+ I think it should work out of the box if the new changes are to be merged, but it could be a good idea to double check. For example the direction and passed value reported by the x11 (and drm as soon as I update it as well) compositor are inverted increased to an arbitrary delta (10.0 so far). Touchpads should report similar events as motion events.

Just wanted to give a heads up about this.

Jonas
