The ClutterX11XInputEventTypes enumeration has been unused inside
Clutter for the past 4 years and a half, since we switched to the
XInput 2 API.
The enumeration itself has always been private, and nobody should
have used it in the first place, but if something breaks, we can
revert this commit.
They should be part of the backend-specific API.
The only backend that has an enumeration type is the X11 one, and it's
small, so we can simply put it there.
This is not an ABI change: the backend-specific symbols are still in
the same SO. You'll be required to import clutter-x11.h to have access
to the GType method at the source level, whereas before just importing
clutter.h would have sufficed. The only user of that enumeration was a
function declared in clutter-x11.h, anyway.
Commit 79849ef1d5fff9acd310cd68d59df0c7cf2cb28f had a typo in the
device property format check. This property is formated in 8-bit
items, not 32-bit.
This went unnoticed till now because some touchpads were still being
detected as such due to a second check below:
else if (strstr (name, "touchpad") != NULL)
source = CLUTTER_TOUCHPAD_DEVICE;

Add clutter_x11_set_use_stereo_stage() that can be called
before clutter_init() so that the CoglDisplay we create and all
stages created from that CoglDisplay will be created with a
stereo fbconfig.
This is done in clutter-x11 because of the similarity to the
existing clutter_x11_set_use_argb_visual(), and because it's
not clear without other examples whether the need to have
stereo enabled from before clutter_init() is universal or
somethign specific to GLX.
Cogl required version is increased to 1.20, which has the
required API.

The core pointer concept doesn't really exist anymore in an XI2 world,
so the clutter API is a bit of a mismatch with what X provides. Using
XIGetClientPointer doesn't really help, as far as i can tell the
semantics of XIGetClientPointer are essentially: Whatever the X server
picked when it had to reply with device-dependant data to a query
without a device specifier. Not very useful...
To make matters worse, whether XIGetClientPointer returns a valid
pointer depends on whether there has been a query that forced it to pick
one in the first place, making the whole thing pretty non-deterministic.
This patch changes things around such that instead of using
XIGetClientPointer to determine the core pointer, we simply pick the
first master pointer device. In practise this will essentially always
be the X virtual core pointer.

XIGetClientPointer() may return the device id '0' when called early.
This patch makes pointer cursors work in nested mutter Wayland
sessions again.

If a touchpad is not multitouch, or does not report MT axes (eg. through
the libinput driver), resort to name matching before falling back to
CLUTTER_POINTER_DEVICE.

If the device manager is created and queried for the client pointer at
a very early stage in application lifetime, the device_id returned would
be 0 as the server hasn't apparently decided yet about the client pointer.
For these situations, doing XSync prior to fetching the client pointer
gets the server to device about the client pointer before we query it.

When an application sets the scaling factor manually we should mark it as fixed
and not override it when the xsettings change. This matches GDKs behaviour.
In order for this to work we cannot use the same path when setting the value
internally so introduce a _clutter_settings_set_property_internal and use it
for that.

Until now, touch events sort of rely on XI_Enter/XI_Leave events accompanying
the pointer emulating touch in order to have a stage set on the device, These
events won't happen though if it's not a pointer emulating touch which happens
on the stage, causing touch events to be ignored.
Fix this by ensuring that the input device has a stage on XI_TouchBegin itself,
but only if it's not already set, so we don't possibly steal touch events to
an already interacting stage.

The coordinates translated by the XI2 device manager were being clamped using
the X window size kept by StageX11. However, when the stage is fullscreen,
that size is not updated to the screen size, but kept the same in order to
allow going back to it when the stage goes out of fullscreen.

All backends follow the same pattern of queueing events first in
ClutterMainContext, then copying them to a ClutterStage queue and
immediately free them. Instead, we can just pass ownership of events
directly to ClutterStage thus avoiding the allocation and copy in
between.

We should use the Xkb API to query the direction of the key map,
depending on the group. To get a valid result we need to go over
the Unicode equivalents of the key symbols for each group, so we
should cache the result.
The code used to query and cache the key map direction is taken
from GDK.

Currently clutter_device_manager_xi2_get_core_device always
does a round trip to query the client.
So avoid that by caching the client pointer and only update it when the
xi devices change.

Due to the way add_device() invariably adds to the master/slave device
lists, while keeping ClutterInputDevices 1:1 with device IDs, it may
leave invalid pointers in the list if add_device() is called multiple
times for the same device ID. There are two situations where this may
happen:
1) If devices are disabled and later enabled: devices are added invariably
to the master/slave lists on constructed(), but then on XIDeviceEnabled
they'd get added yet again.
2) Racy cases where the ClutterDeviceManager is created around the same time
XIHierarchyEvents are sent. When getting the XIDeviceInfo on constructed(),
these devices may already appear as enabled, even though XIDeviceEnabled
is seen through XIHierarchyEvents processed in the event loop sortly after.
This last case can be seen when starting gnome-shell on a different tty,
and entering in the one it's been spawned on, clutter initialization
happens around the same time devices are added back because of the tty
switch, and multiple extra ClutterInputDevices are created.

If we get a change in the window scaling factor we want to resize the
backing store of each stage, so we use the notification on the
ClutterSettings:window-scaling-factor property to do so.

The state that the X server sends for button events, by specification,
contains the button state before the event. We need to synthesize in
the result of the event in order to determine what the current button
state is.

XFixesShowCursor / XFixesHideCursor does not actually take the suppled
window argument into account -- the effect is actually global. Use
XDefineCursor instead.

For some XI2 we do not have a Stage associated to the event window.

On high DPI density displays we create surfaces with a size scaled up by
a certain factor. Even if the contents stay at the same relative size
and position, we need to compensate the scaling both when changing the
surface size, and when dealing with input.

When talking to other applications or serializing the modifier
state (and in particular when implementing a wayland compositor),
the effective modifier state alone is not sufficient, one needs
to know the base, latched and locked modifiers.
Previously one could do with backend specific functionality
such as clutter_device_manager_evdev_get_xkb_state(), but the
problem is that the internal data structures are updated as
soon as the events are fetched from the upstream source, but
the events are reported to the application some time later,
and thus the two can get out of sync.
This way, on the other hand, the information is cached in the
event, and provided to the application with the value that
was current when the event was generated.

This removes a bit of work that we have to do for every device, and makes it
easy for mutter to patch out parts of the event mask it doesn't want.
