Eventually we want to have all the high-level code documentation in the
component API reference documentation. However, gi-docgen is currently
missing support for mermaid so we just keep the files in `doc/` and link
to them from `code-overview.md`.

For tablet device, the tool was created when the "Wacom Serial IDs" prop
changed values. This property does not exist on the xf86-input-libinput
driver but v1.5.0 of that driver has a different property for the serial.
The serial is constant (the driver creates one X device per serial), so
we can fetch it after device creation and set it then. For earlier
versions of the driver we assign the random serial 0xffffffaa - good
enough to have at least a tool.
This fixes the crash in #3120 - clutter_event_motion_new()
overrides event->device to the tool's device (if any). Without a tool
motion events use the Virtual Core Pointer instead and our source device
is never added to the stage's priv->pointer_devices.
When we generate an crossing event (which uses the source device) we
fall afoul of an assert in clutter_stage_update_device() that expects
our source device to be in priv->pointer_devices.

The slightly different styles in the different build files make it
harder to reason about or share c_args.
This notably ensures we never set any extra c_args for plain builds and
fixes the cc.get_supported_arguments() check in Cogl, Clutter and Mtk.

Simply reinterpreting the bytes differently is a strict-aliasing
violation if the type of the object isn't char or the target type of the
reinterpretation. None of that is the case here, so we have to resort to
a memcpy.

DRM's kms atomic code was updated to include an API to set the mouse
cursor hotspot. This has historically been missing in the atomic kms
which meant that the virtualized drivers which require mouse cursor
hotspot info to properly render had to be put on a deny list and
had to fallback to the legacy DRM kms code.
Implement the new hotspot API by checking whether the device supports
hotspot properties and if it does set them on the cursor plane. This
enables atomic kms on all virtualized drivers for kernels where
mouse cursor hotspots are in drm core.

Add META_KMS_PLANE_PROP_HOTSPOT_[X,Y] properties
to the MetaKmsPlaneProp enumeration, and
properly initialise them.
Also, add a convenience method in meta-kms-plane
(i.e., `meta_kms_plane_supports_cursor_hotspot`)
to check whether a plane supports hotspot
property setting.

Based on the pressure curve control points sample a bezier curve and
then look up the pressure at that point of the curve.
We sample 256 points and do linear interpolation in between, this
strikes a balance between having to calculate the point for all
8K pressure points a modern pen supports while still giving us
reasonable detailed curves.
