Multitouch wiki pages?

[Ping Cheng]

Hi Rafi,

Thank you for the great suggestion. Please let me know if there is
anything in the existing Wacom driver that we can move to the generic
MT support in the server or in evdev.  I would love to see an unified
generic MT support in Xorg for all touch devices.
