This test ensures that
"pixman-renderer: half-fix bilinear sampling on edges"
keeps on working.
Unlike in the original report
https://gitlab.freedesktop.org/wayland/weston/issues/373, here we use buffer
scale 2 instead of output scale 2 to trigger bilinear filter. The effect is the
same, the actual resulting image in the failing case is just a little
different. This is so that it will be easy to add more viewport screenshooting
tests in this program in the future.

There will be a new test program using viewports and would like to share this
bit of code.
There are two behavioral changes:
- Compositor wp_viewporter interface version is no longer checked.
- client_create_viewport() does not leak the viewporter object.
test_viewporter_double_create needs to call bind_to_singleton_global() itself
so that the viewporter object still exists when the error event arrives.
Otherwise error verification fails.

When weston-desktop-shell uses a solid color for the wallpaper, it creates a
1x1 buffer and uses wp_viewport to scale that up to fullscreen. It's a very
nice memory saving optimization.
If you also have output scale != buffer scale, it means pixman-renderer chooses
bilinear filter. Arguably pixman-renderer should choose bilinear filter also
when wp_viewport implies scaling, but it does not. As w-d-s always sets buffer
scale from output scale, triggering the bilinear filter needs some effort.
What happens when you sample with bilinear filter from a 1x1 buffer, stretching
it to cover a big area? Depends on the repeat mode. The default repeat mode is
NONE, which means that samples outside of the buffer come out as (0,0,0,0).
Bilinear filter makes it so that every sampling point on the 1x1 buffer except
the very center is actually a mixture of the pixel value and (0,0,0,0). The
resulting color is no longer opaque, but the renderer and damage tracking
assume it is. This leads to the issue 373.
Fix half of the issue by using repeat mode PAD which corresponds to OpenGL
CLAMP_TO_EDGE. GL-renderer already uses CLAMP_TO_EDGE always.
This is only a half-fix, because composite_clipped() cannot actually be fixed.
It relies on repeat mode NONE to work. It would need a whole different approach
to rendering potentially non-axis-aligned regions exactly like GL-renderer.

As in aaf35586f4, we want to fail when we are passed an invalid

When a test fails and it produces a difference image, also compute the min/max

If the output only has a single weston_head attached to it, take its
declared transform as the default transform.
With the previous patches, this allows a device declaring the KMS 'panel
orientation' property (e.g. through DeviceTree) to autoconfigure to the
correct display rotation when running Weston.

The KMS 'panel orientation' property allows the driver to statically
declare a fixed rotation of an output device. Now that weston_head has a
transform member, plumb the KMS property through to weston_head so the
compositor can make a smarter choice out of the box.

If an invalid transformation is provided for an output, fail the output
configuration rather than continuing on using whatever we chose as the
default transform.
After !383, this will result in configurations using the old definition
failing and exiting, rather than continuing on the wrong way around.

Regardless of the default transform passed in, weston_parse_transform
would always return 'normal' if there was an output section. This is
because, if a section was declared for that output, it would ask
weston_config for the transform, with the default being 'normal'.
Fix it so we return the passed-in default transform when we have a
matching output section without a transform key. If the transform is
declared but invalid, we can remove the line resetting to the default
transform, because we've already set the default transform up top.

This goes through all output transforms with two different buffer transforms
and verifies the visual output against reference images.
This commit introduces a new test input image 'basic-test-card.png'. It is a
small image with deliberately odd and indivisible dimensions to provoke bad
assumptions about image sizes. It contains red, green and blue areas which are
actually text that makes it very obvious if you have e.g. color channels
swapped. It has a white thick circle to highlight aspect ratio issues, and an
orange cross to show a mixed color. The white border is for contrast and a 1px
wide detail. The whole design makes it clear if the image happens to be rotated
or flipped in any way.
The image has one pixel wide transparent border so that bilinear sampling
filter near the edges of the image would produce the same colors with both
Pixman- and GL-renderers which handle the out-of-image samples fundamentally
differently: Pixman assumes (0, 0, 0, 0) samples outside of the image, while
GL-renderer clamps sample coordinates to the edge essentially repeating the
edge pixels.
It would have been "easy" to create a full matrix of
every output scale & transform x every buffer scale & transform, but that
would have resulted in 2 renderers * 8 output transforms * 3 output scales *
8 buffer transforms * 3 buffer scales = 1152 test cases that would have all
ran strictly serially because our test harness has no parallelism inside one
test program. That would have been slow to run, and need a lot more reference
images too.
Instead, I chose to iterate separately through all output scales & transforms
(this patch) and all buffer scales & transforms (next patch). This limits the
number of test cases in this patch to 56, and allows the two test programs to
run in parallel.
I did not even pick all possible scale & transform combinations here, but just
what I think is a representative sub-set to hopefully exercise all the code
paths.

It turns out that if the client is not explicitly destroyed, it will remain
connected until the compositor shuts down because there is no more a client
process that would terminate.
Usually this is not a problem, but if a test file has multiple screenshooting
tests, the windows from earlier tests in the file will remain on screen. That
is not wanted, hence implement client destruction.
To properly destroy a client, we also need a list of outputs. They used to be
simply leaked. This does not fix wl_registry.global_remove for wl_outputs, that
is left for a time when a test will actually need that.
This patch makes only ivi-shell-app test use the new client_destroy() to show
that it actually works. The added log scopes prove it: destroy requests get
sent. Sprinkling client_destroy() around in all other tests is left for a time
when it is actually necessary.
ivi-shell-app is a nicely simple test doing little else, hence I picked it.

The string from get_test_name() can be used for writing screenshot files and
others. Starting the name with the fixture number makes an alphabetized listing

Let's change the test name to begin with the test (source) name with fixture
and element numbers as suffixes. That makes a file listing easier to look

It was discovered in issue #99 that the implementations of the 90 and 270
degree rotations were actually the inverse of what the Wayland specification
spelled out. This patch fixes the libweston implementation to follow the
specification.
As a result, the behaviour of the the weston.ini transform key also changes. To
force all users to re-think their configuration, the transform key values are
also changed. Since Weston and libweston change their behaviour, the handling
of clients' buffer transform changes too.
All the functions had their 90/270 cases simply swapped, probably due to
confusion of whether WL_OUTPUT_TRANSFORM_* refers to rotating the monitor or
the content.
Hint: a key to understanding weston_matrix_rotate_xy(m, c, s) is that the
rotation matrix is formed as
c -s
s c
that is, it's column-major. This fooled me at first.
Fixing window.c fixes weston-terminal and weston-transformed.
In simple-damage, window_get_transformed_ball() is fixed to follow the proper
transform definitions, but the fix to the viewport path in redraw() is purely
mechanical. The viewport path looks broken to me in the presence of any
transform, but it is not this patch's job to fix it.
Screen-share fix just repeats the general code fix pattern, I did not even try
to understand that bit.

Make stream_destroy() use weston_log_subscriber_release().
This avoids code duplication and allow us to destroy
weston_log_subscriber_get_only_subscription(), since it's
being used only in this case and it's internal.
Calls for weson_log_subscriber_release() leads to
weston_log_debug_wayland_to_destroy(), which should not
send an error event when the stream has already been closed.
Also, stream_destroy() shouldn't lead to an event error, as
it is a wl_resource destroy handler. So close the stream before
calling weston_log_subscriber_release() in stream_destroy()

Log subscriber API is not type-safe. File and flight recorder
subscribers are created with functions that return
weston_log_subscriber objects. But there's a problem: to destroy
these objects you have to call the right function for each type
of subscriber, and a user calling the wrong destroy function
wouldn't get a warning.

weston_log_subscriber has a member named destroy. There are
other structs (weston_output, for instance) that have this
member, and by convention it is a pointer to a function
that destroys the struct.
In weston_log_subscriber it is being used to destroy
subscriptions of the debug protocol, and not the subscriber,
so this name is misleading. Rename it to destroy_subscription.

The cms-static, desktop-shell, hmi-controller, ivi-shell, and screen-share
modules use symbols from libexec_weston, e.g.:
$ ldd /usr/lib/x86_64-linux-gnu/weston/desktop-shell.so | grep "not found"
libexec_weston.so.0 => not found
Loading these modules from weston happens to work because the weston executable
itself links against libexec_weston, and has an rpath set. Still, these modules
depend on a library in a non-standard location. Adding an rpath could help
static checkers to make sure all shared objects' dependencies are present.

This adds the necessary fuzz to image matching to let GL-renderer pass.
The difference is due to rounding. weston-test-desktop-shell.c uses
weston_surface_set_color(dts->background_surface, 0.16, 0.32, 0.48, 1.);
to set the background color. Pixman-renderer will truncate those to uint8, but
GL-renderer seems to round instead, which causes the +1 in background color
channel values.
0.16 * 255 = 40.8
0.32 * 255 = 81.6
0.48 * 255 = 122.4
