grail v1.0.17

Use a unified pointer emulation model

The existing kernel MT devices together use a handful of different
pointer emulation strategies, each with its own subtlety. This creates
a problem for grail, which needs to rebuild pointer emulation during
gesture recognition; relying on the correct pointer information to be
available at the right time becomes almost impossible.

This patch implements a common pointer emulation model for grail,
following a strategy recently discussed on LKML. This resolves the
problems stemming from different emulation strategies, and results
in a common pointer emulation experience for all devices.

Report touch down on one-finger entry (LP: #667802)

The current code mistakenly set the pointer logic based on
the single variable, which is false at the entry to one-finger
mode, but true immediately afterwards. This leads to grail
sometimes failing to emit the proper emulation sequence, resulting
in a missed touch in X.

This patch corrects the logic such that the pointer is based directly
on one-finger mode, thereby solving the problem.

Only support pure absolute devices at this time

There are some hybrid relative/absolute devices out there, like
the magic mouse, for which special behavior, outside the current
scope of grail, is expected. This patch disables grail for those
devices.

Show all information for pass-through events

In grail-gesture, the timing information is missing. Remedied with
this patch.

Add tap state to the tapping model

Add the ability to read off the tap state in the tapping
model. Useful for emulation i lieu of tapping gestures.

Add tap emulation

Touchscreens always emit a button event when touching the
screen. Trackpads, however, are considered hovering while
touching the pad, and instead uses taps to emits button events,
which is traditionally implemented elsewhere, and thus leaves
a functionality discrepancy. This patch adds tap emulation to
grail, utilizing gesture engine.
