The test makes sure the YCbCr formats create the expected image and we
don't accidentally break it.
Like all wayland tests, this is now part of mutter/wayland, mutter/tty,
and mutter/kvm and will use either shm or dma-buf depending on which
suite is chosen.

We want to run those tests in VKMS later with the same reference image.
To make the tests as close to each other as possible we use the same
resolution for the VKMS and the virtual output which is 640x480.

This test currently only works because the monitor has the same width
and height. Generalize it to arbitrary monitor sizes by taking into
account that width and hight are swapped for some rotations.

It tests various sub-surface corner cases. It would fail without the
previous fixes.
v2:
* Fix draw_descendant parameter formatting
* Make toplevel window fullscreen (Robert Mader)

The testing currently done is:
* Creating a virtual monitor succeeds and gets the right configuration
* Painting a few times results in the expected output
* Changing the content of the stage also changes the painted content
accordingly
* Destroying the virtual monitor works as expected

This adds a test framework that makes it possible to compare the result
of painting a view against a reference image. Test reference as PNG
images are stored in src/tests/ref-tests/.
Reference images needs to be created for testing to be able to succeed.
Adding a test reference image is done using the
`MUTTER_REF_TEST_UPDATE` environment variable. See meta-ref-test.c for
details.
The image comparison code is largely based on the reference image test
framework in weston; see meta-ref-test.c for details.
