6d699c3f54 libweston: add weston_backend::shutdown callback
Add a weston_backend::shutdown callback to split out the part of
weston_backend::destroy that needs to be done before compositor
shutdown.

03596a9d06 libweston: Add initial tablet support to weston
Introduces three new structs, weston_tablet and weston_tablet_tool for the
respective devices, with the respective information as it's used on the protocol.
And weston_tablet_tool_id to track the tools of a tablet.

Note that tools are independent of tablets, many tools can be used across
multiple tablets.

The nesting on the protocol level requires a global tablet manager, a tablet
seat nested into weston_seat. The list of tablets and tools are also part of
the weston_seat.

Most functions are stubs except for the actual tablet and tablet tool
creation and removal.

This is based on patches from Peter Hutterer <peter.hutterer@who-t.net> and
Bastian Farkas <bfarkas@de.adit-jv.com>.

8031b9d57f backend: Make input notification functions use weston_coord
Push weston_coord into the notification functions instead of passing
two doubles.

The touch handlers are passed a pointer to a weston_coord, which is
unusual. This is done so we can pass a NULL pointer instead of a
fabricated invalid coordinate when the touch type is TOUCH_UP.

4d0ce16669 libweston: replace weston_output_transform_coordinate
This creates a global coordinate from a device coordinate.

Replace it with weston_coord_global_from_output_point() which
does the same thing and returns a weston_coord_global.

e1b4ad7d0b matrix: Introduce weston_coord
All through weston we have code that passes int x, y or
float x, y or wl_fixed_t x, y pairs. These pairs are frequently
converted to/from wl_fixed_t and other types.

We also have struct vec2d and struct weston_geometry which also
contain coordinate pairs.

Let's create a family of coordinate vector structures for coordinate
pairs and use it anywhere we sensibly can.

This has a few benefits - it helps remove intermediate conversion
between fixed/float/int types. It lets us roll the homogenous
coordinate normalization bits into helper functions instead of
needing them open coded throughout the source.

Possibly most importantly, it also allows us to do some compile time
validation of what coordinate space we're working in.

6f977640e6 libweston, backends: pass backend parameter to weston_backend functions
Passing the backend as a parameter to the weston_backend function
pointers seems more natural and will be very useful once there can be
more than one backend.

Since all backends already store a pointer to the compositor instance,
replace the compositor parameter with the backend in all functions.

2ca2eac39a libweston: Split notify_pointer focus into notify/clear
This lets us say what we really mean instead of passing a NULL output
and garbage co-ordinates.

This will help later when manufacturing garbage coordinates becomes much
harder to do.

The clear_pointer_focus() path continues to do nothing, and is just a FIXME
macro, as it has been for a very long time...

342afb390b libweston: rename weston_output_region_from_global
Rename weston_output_region_from_global to weston_region_global_to_output,
and also no longer modify in place.

Trying to make it look a little nicer, as well as making it easier to use
from other places that don't want modify in place semantics.

This becomes a very thin wrapper around weston_matrix_transform_region.

cea53a90d4 libweston: add HDR metadata to weston_output
This adds hdr_meta field in weston_output_color_outcome. This field is
intended to be set by color manager modules, and read by backends which
will send the information to the video sink in SMPTE ST 2084 mode a.k.a
Perceptual Quantizer HDR system.

Such metadata is essential in ST 2084 mode for the video sink to produce
a good picture.

The validation of the data and the group split is based on the HDR
Static Metata Type 1 definition in CTA-861-G specification.

5f9b68d68f libweston: introduce weston_eotf_mode
This is the switch to turn HDR mode on.

The values in the enumeration come straight from CTA-861-G standard.
Monitors advertise support for some of the HDR modes in their EDID, and
I am not aware of any other way to detect if a HDR mode actually works
or not. Different monitors may support different and multiple modes.
Different modes may look different. Therefore the high-level choice of
how to drive a HDR video sink is left for the Weston frontend to decide.

All the details like what HDR metadata to use are left for the color
manager.

This commit adds the libweston API for backends to advertise support and
for frontends to choose a mode. Backend and frontend implementations
follow in other commits.

The frontend API does not limit the EOTF mode to the supported ones to
allow experimentation and overriding EDID.

6ee6e76a0c compositor: remove repaint_data from compositor
The repaint_data is entirely backend specific. Moreover, it is only used by the
drm backend, while other backends ignore the repaint data.

There will always be only one repaint active, thus, there is no need to pass the
repaint data from the outside.

The repaint_data breaks with the multi-backend series, which calls repaint begin
for all backends to get the repaint_data. The repaint_data of the last backend
will then be passed to all other backend. At the moment, this works, because the
drm backend is the only backend that implements the begin_repaint call.

Another option would be to track the repaint data per backend in the compositor,
but actually, it the backend needs to track state across the calls, it's its own
responsibility.

66374d48f1 compositor: Remove desktop zoom
Zoom is a neat trick, but in its current form it's very hard to test
and maintain.

It also causes output damage to scale outside of the output's boundaries,
which leads to an extra clipping step that's only necessary when zoom
is enabled.

Remove it to simplify desktop-shell and compositor.

5a701547a4 libweston: Add the ability to determine if a dmabuf is scanout-capable
Adds a new callback 'can_scanout_dmabuf' in weston_backend, which
can be set by the back-end do determine if the buffer supplied can be
imported directly by KMS.

This patch adds a wrapper over it, 'weston_compositor_dmabuf_can_scanout'
which is called before importing the dmabuf in the GPU if the
direct_display dmabuf is being set. If that's true and the check
failed, we refuse to create a wl_buffer.

This patch avoids importing in the GPU.
