New function that transforms a pixman_box32_t rectangle by a matrix.
Since pixman rectangles are represented by 2 corners, non-90 degree
rotations can't be properly represented. This function gives the
axis aligned rectangle that encloses the rotated rectangle.
We use this for weston_matrix_transform_region(), simplifying it and
allowing it to work for non 90 degree rotations.

As things are, even when mode=current is specified on the .ini file,
a full modeset is needed (and done), which causes a very noticeable
screen blinking. That is because setting the max_bpc on a connector
needs full modesetting.
The idea here is that if mode=current on the .ini, no modesetting
should be done, so the current max_bpc is programmed into the
connector.
But if a custom max-bpc=... is specified, that will be used instead,
even if mode=current on the .ini

Surface views that are not assigned to a layer are not going to be
rendered, and thus should not participate in determining the outputs the
surface is on.
There are other view properties that may determine if the view should be
considered in output_mask calculations, e.g., is_mapped, but checking
for this currently breaks tests. Such additional checks are left for
future fixes or reworkings of the view infrastructure.

The planes in the plane_list must be sorted from largest zpos_max to smallest.
Currently the plane order is only correct when the planes are already ordered
and added starting with the smallest zpos_max. This works accidentally in most
cases because the primary plane is usually first and there is often only one
overlay plane or the zpos is sufficiantly configurable.
To fix this, insert a new plane before the first plane with a smaller zpos_max.
And if none is found, insert it at the end of the list.

With the help of a newly introduced function, weston_desktop_surface_set_orientation(),
this patch adds missing tiled states from the xdg-shell protocol.
The orientation state is passed on as a bitmask enumeration flag, which the
shell can set, allowing multiple tiling states at once.
These new states are incorporated the same way as the others, retaining
the set state, but also avoiding sending new configure events if nothing
changed since previously acked data.

Changing the mode will destoy the GBM surface for the output. As a result all

When an atomic commit fails then the output will be stuck in
REPAINT_AWAITING_COMPLETION state. It is waiting for a vblank event that was
never scheduled.
If the error is EBUSY then it can be expected to be a transient error. So
propagate the error and schedule a new repaint in the core compositor.
This is necessary because there are some circumstances when the commit can fail
unexpectedly:
- With 'state_invalid == true' one commit will disable all planes. If another
commit for a different output is triggered immediately afterwards, then this
commit can temporarily fail with EBUSY because it tries to use the same
planes.
- At least with i915, if one commit enables an output then a second commit for a
different output immediately afterwards can temporarily fail with EBUSY. This
is probably caused by some hardware interdependency.

As wayland-backend is blitting the output decorations into the output
buffer itself, it pretends towards the pixman-renderer that there is no
decorations area. The pixman_image_create_bits() call wraps the
previously allocated buffer with an offset so that pixman-renderer will
paint in the right position.
The bug is that this pixman image was using the original buffer width
and height, instead of the composited area width and height. So the
pixman image looks too big to pixman-renderer, but the renderer didn't
care. The image being too big does risk access out of bounds in
pixman-renderer.
I found this when I was making renderers explicitly aware of the
frambuffer size and resizing, added asserts, and they surprisingly
failed. This fixes that.

Everywhere we are standardising to drm_fourcc.h pixel format codes, and
using struct pixel_format_info as a general handle that allows us to
access the equivalent format in various APIs. In the name of
standardisation, convert weston_compositor::read_format to
pixel_format_info.
Pixman formats are defined CPU-endian, while DRM formats are defined
always little-endian. OpenGL has various definitions. Correctly mapping
between these when the CPU is big-endian is an extra chore we can
hopefully offload to pixel-formats.c.
GL-renderer read_format is still defined based on Pixman format, because
of the pecualiar way OpenGL defines a pixel format with
GL_UNSIGNED_BYTE. That matches the same Pixman format on big-endian but
not the same drm_fourcc.

A following patch is going to need the introduced 'area' and 'fb_size'

While starting to use struct weston_geometry, convert also the input and
opaque regions to use it. This shortens and simplifies the code, as we
can drop the roughly duplicate code of doing stuff for with vs. without
a frame.
No change in behavior, this is pure refactoring.

The paint_node_z_order_list contains all views, not just the ones visible on the
current output. So all views are moved to the primary plane when one output
does not support planes.
This will be relevant with multiple backends: When an output without plane
support is rendered then the views of all other outputs are removed from
the current planes and the corresponding outputs will be repainted
unnecessarily.
So only reset the plane if the view is actually on the current output.

This patch acts as bandaid in the core compositor to avoid the renderer

When an output is destroyed then the output state is freed immediately. In this
case, the plane state is only partially destroyed because it is the currently
active state. This includes the buffer reference.
Without the output, the plane will not be updated any more until it is used by a
different output (if possible) or the output returns and the plane is used
again.
As a result, the buffer reference is kept for a long time. This will cause some
applications to stall because weston now keeps two buffers (the one here and
another one for a different output where the application is now displayed).
To avoid this, do a synchronous commit that disables the output. The output
needs to be disabled anyways and this way the current state contains no
buffers that would remain.
`device->state_invalid = true` in drm_output_detach_crtc() is no longer
needed, because drm_output_detach_crtc() is called only when initialization
failed and the crtc was not yet used or in drm_output_deinit() when the
crtc was already disabled with the new synchronous commit.

noop-renderer needs to actually access the buffer content, to ensure
that the bad-buffer test works. This was previously done using a
volatile variable, but clang rightly pointed out that the variable
access had no effect (since the volatile stack variable was never read
from, and the source is not volatile), so 9b0b5b57dd changed it to be
explicitly marked it as unused to suppress the compiler warning.
Unfortunately suppressing the warning still leaves the compiler free to
optimise out the access.
Replace the variable decorations with actually using the result of the
read, so we can be really sure that it's never going to be optimised
away.
