X Input 2.2 Is Ready To Be Touched

It looks like X Input 2.2 with proper multi-touch support is ready to be shipped in the soon-to-be-released X.Org Server 1.12.

Last night Peter Hutterer sent in the final batch of clean-ups for X Input 2.2-related work. The big feature of this X Input extension update is the proper multi-touch support, which up to this point wasn't in the mainline X.Org Server and Canonical also had their own custom implementation for Ubuntu. Now thanks to the work of Peter, Daniel Stone, and Chase Douglas, the mainline support appears in good shape.

As Peter wrote in XI 2.2 last bunch of cleanups, "Just cleanups in the spec document, there isn't anything exciting in there and no actual changes to the protocol. Other than these, I think 2.2 is done."

X.Org Server 1.12 with X Input 2.2 is set to be officially released in early March. Besides the input advancements, there unfortunately isn't too much to get excited about for the 1.12 release, as there is still missing features.
