Bookworm has just been released. Add jobs which start using it, but keep
bullseye around as the LTS release, to make sure we can build on new and
old distributions.

Debian bookworm needs a newer version of Mesa to build against LLVM 15.
Upgrade Mesa and the kernel whilst we're at it, just to make sure that
things keep working.

Newer versions of Debian make you pass --break-system-packages to pip in
order for it to install packages. Since we do want to keep using pip for
controlled versions rather than the distribution packages, add this
flag.

Until now we've only had the unadorned arithmetic functions, but they're
easy to abuse and tedious to use.
For now, we just add weston_coord_global_add/sub functions and use them
where appropriate.

This is stored as an unadorned weston_coord internally, but with getter
functions we can put together the appropriate global or surface

Truncating a weston coord to integer values is something we do
frequently enough to warrant a helper function.

The 'confine' client is used to showcase the behavior of pointer confinement
through the interface zwp_confined_pointer_v1.
Since zwp_confined_pointer_v1 is part of pointer constraints in general, which
includes pointer locking, it makes sense to augment the scope of the client so
it can serve as a showcase for this category of interfaces through
zwp_pointer_constraints_v1.
Currently 'confine' relies on, and is designed around the limitations of, the
toytoolkit. Adapting the toytoolkit for the new requirements proved
unproductive, especially since we wish to add support for pointer constraints in
sub-surfaces. Hence the solution adopted was to write a new client that would
replace the previous one.
This patch introduces the new client, 'constraints.c', replacing 'confine.c'.

We need this so that Weston can update the "click to activate" serial, so
that we can then use the constraints protocol (see

When an output is moved, all views that are not moving with it should
cause damage where they appear in it before and after the move, and all
prior damage should move with the output.
To avoid this complexity, just damage the full output after the move.

While the GL renderer is not able to directly render into the PipeWire buffers,
it is possible to read the rendered frame from the fbo into the PipeWire buffer.

clip_quad() is a dedicated clipping function for quads that doesn't
depend on any GL renderer internal structures. It can be moved out to
the clipper to be called by both the renderer and the clipping test
client without having to duplicate code.

Since both the surface rect and the transformed quad are axis-aligned
in the simple clipping path, non-zero area detection can more
efficiently be checked post-clipping by comparing opposite edges.

Add a basic check to let the clipper take the simple axis-aligned path
when nodes are solely transformed with a translation and/or a scaling.
That makes some nodes like sub-surfaces (which always have their
transform enabled) take the fast path in the common case.

Move vertex clipper back to single-precision floating point
intermediates. Since positions are sent down the graphics hardware as
single-precision values, this prevents useless conversions between
single and double precision values and lets compilers fit twice as
much data into vector registers. It also removes a copy by letting the
clipper store vertices directly into the vertex buffer.
This is mostly reverting the conversion to double-precision that
happened along with the switch to the weston_coord struct for vertex
coordinates (commit 10e70bf23c).

The clipper transforms dirty rects to surface space before clipping.
Each dirty rect is transformed by the same matrix for each surface
rect. This change decouples the transformation and the clipping code
to transform and compute the bounding box of dirty rects just once.

Clip dirty rects to surface rects in surface coordinate space.
Dispatch vertices in surface coordinates and let the graphics hardware
handle the transformations. Clipping in global coordinate space
implies a useless roundtrip on the CPU to get the clipped polygons
back in surface coordinates for the buffer transformation. Clipping in
surface coordinate space prevents that.
This might seem counter-intuitive at first because in surface space
it's the dirty rects that are clipped to axis-aligned surface rects,
while it's the opposite in global space.
The projection matrix now combines the view and the output transforms.
