master->last.valuator[x] for x > 2 is undefined. For all other devices, it's
the respective device's last valuators.
If the lastSlave did not have a valuator that is to be updated now, it is
reset to 0.
In GPE, we don't care about the device mode. Let's put the absolute values
into the deviceValuator event and worry about relative valuators on the other
side of the EQ.
Assuming master->last.valuators is in screen coords, SD's are always in device
coordinates.
1. If an event comes in, scale masters->last to the device, drop into device's
last->valuators.
2. Apply motion from the actual event
3. Scale back to screen coords, check if we may need to cross screens
4. Drop screen coords into master->last
5. Rescale to device coords, drop into deviceValuator event and SD->last
6. Drop screen coords into ev->root_x/y
Whoopee...
During GetPointerEvents (and others), we need to access the last coordinates
posted for this device from the driver (not as posted to the client!). Lastx/y
is ok if we only have two axes, but with more complex devices we also need to
transition between all other axes.
ABI break, recompile your input drivers.
Changed all the checks for x&y valuator so the more complex
calculation is only made once.
Added TODOs for valuator/axis 2 and above for future correct
handling of relative reporting of these.

valuators[] is passed from the DDX. Depending on the device mode, update it
with either absolute values or relative values. The deviceValuator event sent
to the client will then contain the respective values.
This isn't quite finished yet, but at least it gives us the ability to use a
tablet as a normal mouse - with all the scaling in place.

Sometimes we didn't have a cursor when coming back from suspend. Reason was
that the suspend caused the server to lose the device that was attached to the
VCP, and a RemoveDevice() would then set the cursor to NULL.
Solution: only set the cursor to NULL if we actually own the sprite.
We pass in the client that wants to create the device anyway, lets use the
parameter instead of hardcoding the serverClient.
Wow. I hope this is merge detritus, otherwise it'd be a sign that I didn't
have enough coffee that day.
XQuartz was crashing because the Appkit thread was trying to GetXXXEvents while the Xserver thread was exiting.
This adds some more sanity checks and avoids that crash
(cherry picked from commit 34ec4bd6ac)
When a new device is added, calculate the event size needed if a DCCE event is
sent and set the EQ's event size to this minimum. This avoids reallocs when a
event is sent (which may happen during a SIGIO).
This variable was used originally to determine which client is allowed to
change the pointer-keyboard pairing. For now, we just let anyone change it and
see how that works out.
(cherry picked from commit 4e2c6dbabdbbaaca213fd08edd422de15d0900cc)
required because of commit 7c0709a736,
which made requestingClient in dix specific to Xprint only.
Add to XPRINT_LIBS in hw/xprint/Makefile.am in front of
$(XSERVER_LIBS) to override definitions in libdix.la for standard xservers.
Follows 571206832d (providing -DXPRINT
to xprint subdirs).
Note it may be possible to restructure the code so that
requestingClient is stored elsewhere than in dix. See discussions
following http://lists.freedesktop.org/archives/xorg/2008-March/033844.html
If this is done it may be possible to revert this commit (if not 571206...).
