Touch resolution is reported to the userland by retrieving the value
from the HID descriptor. But pen resolution is not since it can not
be retrieved. The current Wacom X driver has a resolution table.
To centralize the source of these values, the resolution entries are
added in the wacom_features struct for x and y coordinates respectively.
The values are then reported to the userland.

There are two types of 1FGT devices supported in wacom_wac.c.
Changing them to follow the existing touchscreen format, i.e.,
only report BTN_TOUCH as a valid tool type.
Touch data will be ignored if pen is in proximity. This requires
a touch up event sent if touch was down when pen comes in. The
touch up event should be sent before any pen events are emitted.
Otherwise, two pointers would race for the cursor.
However, we can not send a touch up inside wacom_tpc_pen since
pen and touch are on different logical port. That is why we
have to check if touch is up before sending pen events.

The drivers using the type B protocol all report tracking information
the same way. The contact id is semantically equivalent to
ABS_MT_SLOT, and the handling of ABS_MT_TRACKING_ID only complicates
the driver. The situation can be improved upon by providing a common
pointer emulation code, thereby removing the need for the tracking id
in the driver. This patch moves all tracking event handling over to
the input core, simplifying both the existing drivers and the ones
currently in preparation.

The Bamboo Touch reports a sub-screen resolution of 480x320. The
signal-to-noise ratio is only about 100, so filtering is needed in
order to reduce the jitter to a usable level. However, the low
resolution leads to round-off errors in the EWMA filter, resulting in
extremely jerky pointer motion. This patch explicitly sets a higher
resolution for those devices, and tells this to the completion handler
via a low-resolution quirk.

Add support for the Bamboo Touch trackpad, and make it work with

uses MT slots internally, so the choice of protocol is a given.

Touch enbaled devices share the same product ID with pen. However,
we do not want to post touch events while pen is in prox. To do so,
we used to keep a local static variable to keep track of if pen is
in prox or not. This works fine for Tablet PC devices since there
is only one device attached. With the newer touch enabled regular
tablets, we can not make this assumption any more, i.e, one system
may have more than one identical tablet plugged in.
This patch adds an new entry, shared, into the struct wacom_wac so
touch data can access pen data to locally. This solution assumes
the two tools (touch and pen) of the same ID will be probed one
after the other without interruption in between by another Wacom
device of the same ID.
Replacing WACOM_PKGLEN_PENABLED with WACOM_PKGLEN_GRAPHIRE since
they both represent the same value, 8. This value will be used
for both Tablet PC and Bamboo with touch devices.

Devices supporting both pen and touch features share the same product ID,
but presented as 2 separate input devices. By adding device type to device
name string we can help userspace applications and users differentiate
between them. 'Finger' is used for the touch since touch has been used as
a suffix by userland hotplugging services.
