Tablet Protocol & Weston Support Is Back To Being Baked

Peter Hutterer is back to working on tablet protocol and support for Wayland/Weston. In this context, it's for drawing tablets like the popular Wacom hardware.

There's been some work done before on a tablet protocol while published today was a largely redone version of this protocol. The protocol is largely new, Peter noted, "Too many changes from the last version (a year ago or so), so I won't detail them, best to look at it with fresh eyes."

At the same time he posted thirteen Weston patches for adding tablet support to Weston. In terms of the setup, he explained the design, "Tablet events are sent serially, terminated by a frame event. A toolkit should accumulate them and then pass them on as one struct to the client. We don't do that atm, it may be beyond libtoytoolkit's scope to really integrate this properly. The tablet has a separate cursor. That's a conscious decision since the focus handling on tablets closer to an absolute touch screen than a mouse, but unlike touch you usually want a cursor shape to indicate the precise position."
