Do not use border texture size when we have the area stored. This
decouples border texture size further.
We also have buffer_height available directly from fb_size, so do not
reverse-engineer it.

Compute the border area from the framebuffer size and composited area
only.
Now the border textures can be freely sized while they will be stretched
to fill the respective border areas. In fact, this was already made use
of by having left/right image height=1 as special cases. Now all the
texture dimensions behave the same.
No change in behavior, the values are the same, just computed
differently.

This moves the identical code from draw_output_borders() and
output_get_border_damage() into a new shared function. Reduces code
duplication.
This is a pure refactoring, all the computations stay the same.

This step prepares to share the coordinate computations between
draw_output_borders() and output_get_border_damage(). The use of
weston_output is replaced with gl_output_state, so that when sharing the
code in a new function, it does not need a weston_output.
This stops the function from accessing output->current_mode and use the
gl-renderer tracked frambuffer size and compositing area instead. Not
using current_mode is a small step towards allowing gl-renderer to
render for other targets than an output.
No behavioral changes, all the values are still the same.
See the diagram in gl-renderer.h for the border areas.

This is necessary if you want to resize an output that uses a shadow
framebuffer, instead of destroying and re-creating the renderer state.
Signed-off-by: Pekka Paalanen <pekka.paalanen@collabora.com>
This changes the GL-renderer interface to pass the initial framebuffer
size and compositing area explicitly. All backends are changed to
provide the correct parameters.
GL-renderer mostly does not yet use these values, but later patches
will. The pbuffer path uses it already, because they replaced the
existing fields.
All this is to make GL-renderer aware of the different sizes, so it can
implement the future revision of the screenshooting API.

This will make sure that backends do not forget to tell us about
resizes.
composite_*() functions still read the size from the destination buffer,

This is necessary if you want to resize a Pixman rendered output that
uses the shadow.
Also reset the current hw_buffer to NULL, because surely it needs to
change and we don't want to keep an old buffer live for no reason if
there happens to be one.

Previously renderers were not told when the output (framebuffer they
need to draw) size changed. Renderers just pulled that information out
from weston_output::current_mode when they happened to need it. This
makes some things awkward, like resizing the shadow or intermediate
buffers. In fact, Pixman-renderer does not even support resizing its
shadow buffer, nor does GL-renderer. DRM-backend has to destroy and
re-create the renderer output state anyway, but rdp, x11 and wayland
backends would be natural users of resizing API.
This commit adds an API for resizing with empty implementations. Actual
implementations will be added in following patches for each renderer
while moving parts of resizing code from backends into the renderers.
No-op renderer needs no implementation.
Only wayland-backend has actual resizing code already, and that is made
to call the new API. Unfortunately, Pixman and GL renderers differ: one
does not blit them while the other does. In order to assert the
functionality of each renderer to keep the API consistent,
wayland-backend needs to lie to pixman-renderer. That's not new, it
already does so in wayland_output_get_shm_buffer() where the 'pm_image'
addresses only the interior area instead of the whole buffer.

This is arguably a little nicer without calling the pixman functions
directly.
In the future when we have different datatypes for coordinates in different
spaces, this test will only be valid on global coordinates, so this change
is also a precursor to stronger type validation.

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 seen previous times, with newer doxygen version we seem to be
generating warnings and with it to stop generating documentation
entirely as we have enabled warning as error in the doxygen
configuration file.
By default meson werror build option is not enabled, so users can still
generate documentation when building regularly, and when we'll update to
the same doxygen version we should be able to catch those errors up if
any of them will pile up in between.

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.

All these Doxygen configuration directives raise a deprecation warning
with Doxygen 1.9.5.
Since we have WARN_AS_ERROR = YES, this causes the build to fail.
Remove these deprecated directives.
I have checked the differences by first building from scratch without
this patch, and then building from scratch with this patch, and
in the latter builddir checking
$ diff -ru -x '*.md5' -x '*.pdf' ~/tmp/weston-doc-before doc
The only differences are the Doxygen config file and one .pickle file.
So it seems the generated docs are identical with Doxygen 1.9.1.

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.
