With the added rules, trackpads should be manageable no matter what
occurs (button presses and pointer motion). Gesture and touch semantics
during these actions are not well defined, and cancelling touches cleans
up the protocol and implementation.

The semantics of these grabs doesn't work for all use cases. Raw touch
events will likely work better.

* Wording cleanups for tense and to make some sentences flow better.
* Upon further review, it does seem to make more sense to deliver
emulated pointer events through the same slave device rather than the
master device. Thus, slave devices (including floating devices) may
emit emulated pointer events.
* Peter is correct, it doesn't make sense to set the PointerEmulated
flag on touch events.

Remove IndepedentTouch and SemiMultitouch devices. These may be handled

No functional effect, just to improve readability of code.
It's not obvious what "True" or "False" stands for in a function with 11
arguments. Compare
XIGrabButton(dpy, deviceid, button, grab_window, cursor,
GrabModeAsync, GrabModeSync, True,
event_mask, num_modifiers, &modifiers);
vs.
XIGrabButton(dpy, deviceid, button, grab_window, cursor,

XI 2.0 headers forced clients to mix XI2 specific constants with defines for
core input. Most notable here are the grab code which required GrabModeAsync
or GrabModeSync from core, but _not_ AnyModifier (XIAnymodifier !=
AnyModifier). This is a hard-to-debug cause for bugs.
Add defines for grab modes, grab return codes and property modes as well as
a define for the AnyPropertyType. These defines are identical to the ones
defined in core but stop the use of input-related defines from either core
or XI 1.x.
Clients must use the core defines None and CurrentTime where applicable.

Though this protocol description is mainly to be viewed as textfile, a few
minor changes make it parsable for asciidoc to spit out reasonably
nicely-formatted html code.
Changes include:
- underline section headers with the matching lines
- add linebreaks before lists to parse them as lists
- change indentation level for normal text to be left-marging aligned and
for <pre> text to be indented
- comment out section dividers
It's possible to run asciidoc XI2proto.txt and get some nice html output
now.
