The latter is used to increase the amount of allocated memory for the event
list. This will be needed for ClassesChangedEvents that can be of more or less
arbitrary size (larger than 32 anyway).
Rather than letting the DDX allocate the events, allocate them once in the DIX
and just pass it around when needed.
DDX should call GetEventList() to obtain this list and then pass it into
Get{Pointer|Keyboard}Events.
Relative events that generates both core and extention
events will have its axis cliped and screen changed by
miPointerSetPosition when the events are processed. For
absolute and non core-generating relative events the
axis must be clipped if we shouldn't end up completely
outside the defined ranges (if any).
Don't use a possitive value as a marker for if a max-value
is defined on the valuators. Use the existence of a valid
value range instead. This will also make it possible to
define arbitrary start and end-values for min and max as
long as min < max.
(first_valuator + num_valuators) must never be larger than the number of axes,
otherwise DIX freaks out. And from looking at libXI, anything larger than 6 is
wrong too.

(first_valuator + num_valuators) must never be larger than the number of axes,
otherwise DIX freaks out. And from looking at libXI, anything larger than 6 is
wrong too.
Initialise num_events to 1, so we always send a proximity event, and then
optionally valuator events. Also make sure mieq can deal with valuator
events sent after proximity events.
We free the ValuatorClassRec quite regularly. If a SIGIO is handled while
we're swapping device classes, we can bring the server down when we try to
access lastx/lasty of the master device.
Turns out it's really really hard synchronising device state across multiple
duplicated events if they all share the same struct. So instead of doing so,
when the SD changes deep-copy all it's classes into the MD. The MD then has
the same capabilities, but the state can be set separately. This should fix
xkb, key state, repeat etc. problems.
Updating the device state allows us to remove the SwitchCoreKeyboard from the
event gathering, it's all done during event processing now.
If a slave device is attached to a master device, then we need to send a
mapping notify to the client.
Mapping notify needs to be sent if
- different slave device but on same master
- different master
This gives you funny behaviour with the ClientPointer. When a
MappingNotify is sent to the client, the client usually responds with a
GetKeyboardMapping. This will retrieve the ClientPointer's keyboard mapping,
regardless of which keyboard sent the last mapping notify request. So
depending on the CP setting, your keyboard may change layout in each app...
Each time a different slave device sends through a master, an
DeviceClassesChangedEvent is enqueued. When this event is processed, all
classes of the matching master device are changed, and the event is sent to
the clients.
Next time the master is queried, it thus shows the evclasses of the last slave
device. The original classes are stored in the devPrivates.
TODO: if all slave devices are removed, the master's original classes need to
be restored.
For pointers: don't try to set master->valuator fields if there is no master.
For keyboards: check if device is valid before trying to access the fields in
miPointerGetScreen (btw. this disables DGA events for floating keyboards).
Also stop the hideous number of ErrorFs if we request the paired device for a
floating dev.
Let the drivers only generate XI events and put those into the event queue.
When processing events, generate core events as needed. This fixes a number of
problems with XKB and the DIX in general.
The previous approach was to put core events and XI events as separate events
into the event queue. When being processed, the server had no knowledge of
them coming from the same device state change. Anything that would then change
the state of the device accordingly was in danger of changing it twice,
leading to some funny (i.e. not funny at all) results.
Emulating core events while processing XI events fixes this, there is only one
path that actually changes the device state now. Although we have to be
careful when replaying events from synced devices, otherwise we may lose
events.
Note: XI has precedence over core for passive grabs, but core events are
delivered to the client first.
This removes the wrapping added in 340911d724
Add keyc->postdown, which represents the key state as of the last mieqEnqueue
call, and use it when we need to know the posted state, instead of the
processed state (keyc->down). Add small functions to getevents.c to query and
modify key state in postdown and use them all through, eliminating previously
broken uses.
This reverts commit 6b055e5d97.
MPX relies on the XI event being delivered before the core event. Device grabs
break, amongst other things. I guess stuck modifiers need to be fixed some
other way.

over to new system.
Need to update documentation and address some remaining vestiges of
old system such as CursorRec structure, fb "offman" structure, and
FontRec privates.
