Invert the Y_INVERT flag for the EGL import fo dmabufs. This fixes
weston-simple-dmabuf-intel to show the same image on both GL-composited
and with direct scanout on a hardware plane. Before, the image would
y-flip when switching between these two cases. Now the orientation also
matches the color values written in simple-dmabuf-intel.c.
The GL-renderer uses the OpenGL convention of texture coordinates, where
the origin is at the bottom-left of an image. This can be observed in
texture_region() where the texcoords are inverted if y_invert is false,
since the surface coordinates have origin at top-left. Both wl_shm and
dmabuf buffers have origin at the top-left.
When wl_shm buffer is imported with glTexImage2D, it gets inverted
because glTexImage2D is defined to read in the bottom row first. The shm
data is top row first. This incidentally also means, that buffer pixel
0,0 ends up at texture coordinates 0,0. This is now inverted compared to
the GL coordinate convention, and therefore gl_renderer_attach_shm()
sets y_inverted to true. This causes texture_region() to NOT invert the
texcoords. Wayland surface coordinates have origin at top-left, hence
the double-inversion.
Dmabuf buffers also have the origin at top-left. However, they are
imported via EGL to GL, where they should get the GL oriented
coordinates but they do not. It is as if pixel 0,0 ends up at texcoords
0,0 - the same thing as with wl_shm buffers. Therefore we need to invert
the invert flag.
Too bad EGL_EXT_image_dma_buf_import does not seem to specify the image
orientation. The GL spec implied result seems to conflict with the
reality in Mesa 11.2.2.
I asked about this in the Mesa developer mailing list. The question with
no answers:

which culminated to the conclusion:

that supports this patch.
simple-dmabuf-v4l is equally fixed to not add Y_INVERT. There is no
rational reason to have it, and removing is necessary together with the
GL-renderer change to keep the image the right way up. This has been
tested with VIVID.

libweston has separate version numbering from weston because of
development needs.
During development, weston version is major.minor.90 which will never be
a release version number. While developing, we may break the libweston
backward-compatibility, in which case libweston_major_version will be
bumped. This means that libweston_major_version > weston_major_version
but only during the development period and for the pre-releases. When
the official x.y.0 release is made, weston and libweston versions will
get synchronized as explained in releasing.txt.
The reason we do this is that e.g. during the weston 3.0.90 development
period we must be able to install libweston-4.so because the development
has broken the compatibility and so we cannot install it as libweston-3.so
anymore. However, we cannot bump weston to 4.0.90, because then the
official release would go backwards in numbers to 4.0.0.
This also means that weston pre-releases major.minor.9x may install
libweston-(major+1).so. There is also libweston-(major+1).pc file but it
will give the weston version as the version number. IOW, pkg-config
check for 'libweston-M < M.0.0' matches only the pre-releases of the
libweston major version M. Hence, 'libweston-M >= M.0.0' cannot be
satisfied by pre-releases.
The weston and libweston version numbers MUST be identical in all
releases except the pre-releases major.minor.9x.
When the 1.11.91 pre-release is made, the rules imply that libweston
version will be bumped from 0.0.0 to 1.11.91. The bumping will continue
up to the 1.12.0 release. After the bump to 1.12.90, the libweston
version may be bumped to 2.0.0. Then the rules imply that:
- 1.12.9x pre-releases install libweston 2.0.0
- the next .0 release is 2.0.0 containing libweston 2.0.0
If the 1.12 stable branch will see additional releases, those will be
numbered 1.12.1, 1.12.2, etc. with the libweston version being the same
as the release version number.
If we have release 2.0.91 without libweston major bump, then libweston
version will match the release version, leading up to 2.1.0.

libweston-desktop is an abstraction library for compositors wanting to
support desktop-like shells.
The API is designed from xdg_shell features, as it will eventually be
the recommended shell for modern applications to use.
In the future, adding new shell protocols support will be easier, as
limited to libweston-desktop.
The library versioning is the same as libweston. If one of them break
ABI compatibility, the other will too.
The compositor will only ever see toplevel surfaces (“windows”), with
all the other being internal implementation details.
Thus, popups and associated grabs are handled entirely in
libweston-desktop.
Xwayland special surfaces (override-redirect) are special-cased to a
dedicated layer, as the compositor should not know about them.
All the shell error checking is taken care of too, as well as some
specification rules (e.g. sizes constraint for maximized and fullscreen
surfaces).
All the compositor has to do is define a few callbacks in the interface
struct, and manage toplevel surfaces.

When all outputs are gone and views were created before they
were gone, such views would have no output object assigned and
nothing would assign it later. This makes sure all views are
set as dirty, so they can get an output assigned when an
output gets plugged in, if they didn't have any output assigned.
This change also works when a new output is added even if there already
are outputs in use. A view may be partly off-screen. If the new output
appears at a position where it overlaps an existing view, that view
should get updated.
It is enough to process only the main view_list, because views not on
that list are not shown for the moment and so do not need an immediate
update. Instead, they will get updated later as needed because making an
off-list view to go on-list inherently requires calling
weston_view_geometry_dirty().

A notable difference here is that the existing error checking was
verifying that exactly 10 digits were being read from the lock file,
but the fact that it's 10 digits is just an implementation detail for
how we're writing it. The pid could be a shorter number of digits, and
would just be space-padded on the left.
This change allows the file to contain any number of digits, but it
