This makes sure we update min_allocation in situations where the
width and height passed is smaller than the one set previously
(obviously except for the first time). This has the side effect of
not overwriting pending_allocations such that we correctly resize when
passed a width/height smaller the ones set-up in the past.

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'.

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.

There are V4L2 devices that will output NV12 but will do so using one dma
buffer. To support this, we need to add the same dma buffer twice but with

Also supports situations of 3 planes (e.g. YU12) inside a single dma buffer.

Note that this application does not follow best practices for handling tablet
events. The events are grouped by frame, all processing should be done in the
frame instead of the respective handler.
A good toolkit would accumulate the data in the events and provide them as one
event to the actual client once the frame is received. toytoolkit just hooks
up the handler one-by-one, so we're doing this here as well.

When it comes to a window frame, a tablet tool and cursor act almost
identical; they click things, drag things, etc. The tool type and extra
axes don't serve any use in the context of a window frame, so tablet
pointers share the frame_pointer structures used for the mouse pointer.

Fractional scale is increasingly common in the Wayland ecosystem. Thus,
given simple-egl's role as egl example client, implement support for
the new protocol - even though Weston itself does not support it yet.
Together with buffer_scale and buffer_transform this ensures
simple-egl provides optimally sized and oriented buffers.

There's a comment explaining how to hack the DRM-backend in order to
fake that a certain format is not supported by the KMS device. This is
useful in order to test dma-buf feedback implementations using the
simple-dmabuf-feedback client. But with recent changes on the
DRM-backend, this got outdated.
Drop this comment, as everyone interested in this client is probably
familiar enough with the DRM-backend in order to do that.

The functionality of this screenshooting helper client is kept exactly
the same as before: if you have multiple outputs, some transformed, some
scale, in any layout, this will create a "multi-image" where the
framebuffer (the physical image) of each output is pasted into a row of
images in the order the outputs were advertised thrugh wl_registry.
Output transform or scale are not accounted for. If you have a monitor
rotated sideways, the screenshot will have the image of that monitor
reverse-sideways.
Otherwise the client is almost completely re-written, so trying to read
the diff is not that useful.
The old screenshooting protocol is replaced with the new
weston-output-capture protocol. This makes it unnecessary to listen for
wl_output information (since we do not handle output transform or scale
anyway).
The buffer sizes and formats are dictated by the compositor, which also
means we cannot hardcode the format. Hence, use Pixman for the blitting,
in case it needs to do format conversion. It is good to get rid of
hand-crafted pixel data manipulation code too.
For that reason we also need a pixel format database to convert between
DRM fourcc, wl_shm and Pixman codes. We link to libweston to borrow its
database instead of inventing another partial copy of it. It's weird to
use compositor library private API in a client, but better than the
alternative.
The original code had no tear-down code at all. Now, if everything
succeeds, the program ends with no unfreed memory according to ASan. If
something fails, it still YOLO's it (doesn't free stuff). That's how far
my pedantry carried.
I also did not bother taking output transform or scale into account,
since the old code did not either. It would be nice to create a seamless
image of the desktop with shots rotated and scaled to align, in the max
scale over all outputs. Meh.

The motivations for this are:
- Y_INVERT is not used by most real-world clients.
weston-simple-dmabuf-egl and weston-simple-dmabuf-v4l are one only
known users. Thus this creates a special case just for these demo
clients.
- Some compositors (wlroots) have dropped support for DMA-BUF flags,
so the client no longer runs there.
- Dropping the flag allows compositors to use a KMS hardware plane to
display the buffer.
It keeps the same axis orientation we had in place where we had the
y-invert flag enabled by default, by doing a reflection about x-axis.

If weston-simple-egl is run with the "-b" flag, it will attempt to set
the swap interval to 0 during create_surface. However, at that point, it
will not have made its EGLContext current yet, causing the
eglSwapInterval call to have no effect. To fix this, wait until the
EGLContext has been made current in init_gl before updating the swap
