Most references to the savedScreenInfo array already had the
corresponding screen pointer handy, which meant they usually looked like
"savedScreenInfo[pScreen->myNum]". Adding a field to ScreenRec instead
of keeping this information in a parallel array simplifies those
expressions, and eliminates a MAXSCREENS-sized array.
Since dix uses this data, a screen private entry isn't appropriate.

For absolute input devices (E.G. touchscreens) in multi-head setups,
we need a way to bind the device to an randr output. This adds the
infrastructure to the server to allow us to do so.
positionSprite() scales input coordinates to the dimensions of the shared
(total) screen frame buffer, so to restrict motion to an output we need to
scale/rotate/translate device coordinates to a subset of the frame buffer
before passing them on to positionSprite.
This is done here using a 3x3 transformation matrix, which is applied to
the device coordinates using homogeneous coordinates, E.G.:
[ c0 c1 c2 ] [ x ]
[ c3 c4 c5 ] * [ y ]
[ c6 c7 c8 ] [ 1 ]
Notice: As input devices have varying input ranges, the coordinates are
first scaled to the [0..1] range for generality, and afterwards scaled
back up.
E.G. for a dual head setup (using same resolution) next to each other, you
would want to scale the X coordinates of the touchscreen connected to the
both heads by 50%, and translate (offset) the coordinates of the rightmost
head by 50%, or in matrix form:
left: right:
[ 0.5 0 0 ] [ 0.5 0 0.5 ]
[ 0 1 0 ] [ 0 1 0 ]
[ 0 0 1 ] [ 0 0 0 ]
Which can be done using xinput:
xinput set-prop <left> --type=float "Coordinate Transformation Matrix" \
0.5 0 0 0 1 0 0 0 1
xinput set-prop <right> --type=float "Coordinate Transformation Matrix" \
0.5 0 0.5 0 1 0 0 0 1
Likewise more complication setups involving more heads, rotation or
different resolution can be handled.

Peter wants to get a larger patch sequence put together and I didn't
read past the commit message to see the 'don't take this patch
please'.
This reverts commit 531ff40301.
Some input drivers need to implement an internal hotplugging scheme for
dependent devices to provide multiple X devices off one kernel device file.
Such dependent devices can be added with NewInputDeviceRequest() but they are
not removed when the config backend calls DeleteInputDeviceRequest(),
leaving the original device to clean up.
Example of the wacom driver:
config/udev calls NewInputDeviceRequest("stylus")
wacom PreInit calls
NewInputDeviceRequest("eraser")
NewInputDeviceRequest("pad")
NewInputDeviceRequest("cursor")
PreInit finishes.
When the device is removed, the config backend only calls
DeleteInputDeviceRequest for "stylus". The driver needs to call
DeleteInputDeviceRequest for the dependent devices eraser, pad and cursor to
clean up properly.
However, when the server terminates, DeleteInputDeviceRequest is called for
all devices - the driver must not remove the dependent devices to avoid
double-frees. There is no method for the driver to detect why a device is
being removed, leading to elaborate guesswork and some amount of wishful
thinking.
Though the input driver's UnInit already supports flags, they are unused.
This patch uses the flags to supply information where the
DeleteInputDeviceRequest request originates from, allowing a driver to
selectively call DeleteInputDeviceRequest when necessary.
Also bumps XINPUT ABI.

In order to execute a wire-level ChangeGC request, we need to look up
the resources named by any XIDs in the value-list. Various places in the
server already have pointers to the resources they want to set into the
GC, though, so over time the interface has evolved to accept either XIDs
or pointers, with several different function call signatures used in
different eras.
This patch makes the existing code require pointers to resources rather
than XIDs, and adds a simple wrapper that looks up any XIDs. The old
dixChangeGC API is preserved by delegating to whichever implementation
is appropriate.
This affects error-handling: If any of the XIDs are invalid, then the GC
is unchanged, and its ChangeGC callback is not invoked. This change is
allowed by the protocol spec, which says, "The order in which components
are verified and altered is server-dependent. If an error is generated,
a subset of the components may have been altered."

FreeResource() keeps clientTable[cid].elements up to date with the
number of resources allocated to the client. The other free
resource functions (FreeResourceByType(),
FreeClientNeverRetainResources() and FreeClientResources()) don't
maintain this invariant.
Typically, the only consequence is that the element count is too high
and we end up allocating the hash table bigger than necessary. However,
FreeResource() also relies on the element count to restart the search if
the list of resources has been changed during a resource destruction
callback. Since FreeResourceByType() doesn't update the count, if we call
that from a resource destruction callback from FreeResource(), the
loop isn't restarted and we end up following an invalid next pointer.
Furthermore, LookupClientResourceComplex() and
FreeClientNeverRetainResources() don't use the element count to detect
if a callback deleted a resource and may end up following an invalid
next pointer if the resource system is called into recursively.

An absolute device in relative mode may provide valuators outside of the
axis range. Clipping back into the range prevents screen crossings in a
multi-screen (Xinerama) setup as the required screen edge for crossing is
never met: miPointerSetPosition crosses the screen conditional to the X
coordinate being equal to the screen width or _less than_ 0. While the
former can be met when clipping into the coordinate range and scaling, the
latter cannot, resulting in a mouse pointer that gets stuck on the rightmost
screen.
This patch only applies axis clipping for valuators in mode Absolute. If
relative, we allow the values to get above/below the axis ranges. Doesn't
matter, miPointerSetPosition will reset the values to the allowed range even
if no screen was crossed.
This leads to interesting values provided to clients, the valuator range of
the device resets once a screen is crossed and essentially reflects
the position of the cursor on the screen - scaled into the valuator range.
The values themselves are valid given the range though.
In theory, the XI1 specs require that a relative device has a min/max range
of 0/0. This doesn't really go well with devices that actually can switch
mode between relative and absolute since they would have to reset their axis
range when switching. If multiple XI clients are in use, we have no method
of notifying them about the changes, so other clients may continue to use
the wrong axis ranges (note: XI1 wasn't really designed to have multiple
clients use a device). Expecting all relative devices to have this min/max
of 0 is unrealistic at this point.
So pick what is possibly the lesser of all evils, pass the beer and despair.

Therefore create a null root cursor becomes irrelevant.

A keyboard event from a device with both valuators and keys will be posted
through the VCK. In this case, do not update the slave device coordinates
from the VCK - they're always 0/0. Leave them as-is, for the next pointer
event will continue where it left.

XkbRemoveResourceClient() returns immediately if dev->key is NULL.
CloseDevice calls XkbRemoveResourceClient until it removes all resources.
If we free dev->key and NULL it before XkbRemoveResourceClient, then
infinite loop ensues, and the server appears to hang on exit or crash.

This profile is inspired by the accel code removed from the wacom driver.
It ascends from zero to acceleration, maxing out at threshold. This means you
can control the slope using threshold, which wasn't possible in wacom.
For sanity's sake, threshold should grow with acceleration.
Works best with adaptive deceleration, since otherwise it only generates
acceleration above 1, causing seldom pixel skips.

nonetheless to free the memory associated.

InitValuatorClassDeviceStruct always initializes with the default profile.
The default profile allocs data and adds a few properties which become
obsolete if the profile is changed lateron by the driver.
The property handlers are stored in the device's devPrivates and cleaned up.
Ideally, the property handler ID's could be stored somewhere more obvious,
but that seems to require breaking the ABI.

Currently the XTEST device is limited to the same number of buttons the core
device has. This breaks if a user has a mouse with more than 3 buttons
connected and is using a core client to fake button 8+ presses.
Rather than expecting all clients to fix themselves, just increase the
default number of buttons to 10, which is somewhat a compromise. Ideally,
the XTEST devices should adjust themselves to the highest number of buttons
available on the slave devices (like the master pointers already do), but
that's a taks for another day.
