[PATCH weston 00/19] Basic tablet support in Weston

[Stephen Chandler Paul]

Hi! As some of you have been aware, I have been working on implementing tablet
ssupport in libinput, the wayland protocol and weston. This patchset adds basic
tablet support to weston, along with support in the shell and the window
manager. It should be noted that these patches rely on one of the earlier
patches to libinput that I posted on the mailing list: "tablet: Add
libinput_tablet_has_axis()", along with the tablet-support branch in the git repository for libinput.

As of right now, the following things are still missing/haven't been finished
yet:
* Tablet objects don't ever send a removed event, right now it's up to the
  clients to free the resources for each tool object.
* Tablet tool objects should be separate for each tablet connected that doesn't
  report serial numbers. Right now tablet objects are shared by all tablets
  connected to the system unconditionally.
* The tablet cursor disappears occasionally when moving a window and causing
  the mouse pointer to change images, but reappears the next time a client sets
  a cursor image.
* weston-flower can crash the shell for some reason. It seems that if a tablet
  is turned on, and the first surface the tool comes into focus on belongs to a
  weston-flower instance, the desktop-shell runs into an error and exits. I
  haven't noticed this with anything other then weston-flower though.
* Held down buttons are released when the tool changes focus from one surface
  to another, instead of being held down until they're released.
* Some of the declarations for structs in my code might need to be moved
  around, I'm not sure what the expected guidelines for this in weston's code
  are though.
* A surface argument needs to be added to the proximity_out event, so we can
  tell if the tablet tool is leaving proximity to switch focus to another
  surface, or if it's just exiting proximity.

Review/critique would be appreciated, thank you! ^^

Cheers,
	Lyude
