According to the discussion leading up to the properties interface
(https://lkml.org/lkml/2010/12/15/263), a tablet is a direct pointer
device, as opposed to a touchpad, which is an indirect pointer
device. The distinction determines the direction of two-finger scroll,
for instance. The question is then what behavior should be assigned to
a large tablet without an embedded screen. It should have POINTER set
for sure, but should it also have DIRECT set?

Thanks,
Henrik
