If only the source of a viewport is set, the width and height must
be integer or the protocol mandates that the compositor generate an
error. This is because using only the source is a crop, and the
width and height become the surface size - all surface sizes must
be integer.
Weston was fixed to generate this error in bb32ccc0, however the
test app continued to use fractional co-ordinates when run as
weston-scaler -s (which only sets the viewport source)
This leaves fractional width/height for the other cases, but uses
integer for the crop-only mode. The descriptions in the help text
are still accurate with this change, but weston-scaler -s no longer
exits with an error.

This adds single-symbol compose support using libxkbcommon's compose
functionality. E.g., assuming you have the right alt key defined as
your compose key, typing <RAlt>+i+' will produce í, and <RAlt>+y+= will
produce ¥. This makes compose key work for weston-editor,
weston-terminal, weston-eventdemo, and any other clients that use
Weston's window.* routines for accepting and managing keyboard input.
Compose sequences are loaded from the system's standard tables. As
well, libxkbcommon will transparently load custom sequences from the
user's ~/.XCompose file.
Note that due to limitations in toytoolkit's key handler interface, only
compose sequences resulting in single symbols are supported. While
libxkbcommon supports multi-symbol compose strings, support for passing
text buffers to Weston clients is left as future work.
This largely obviates the need for the weston-simple-im input method
client, which had provided a very limited compose functionality that was
only available in clients implementing the zwp_input_method protocol,
and with no mechanism to load system or user-specified compose keys.

weston-terminal intermittently crashes on startup. This occurs because
some parameters in the weston_terminal structure such as data_pitch,
don't get set to non-zero until the resize_handler() callback gets
triggered. That callback makes a call to terminal_resize_cells(), to
calculate the proper values for these parameters.
On occasion, the resize handler call is slow to resolve, and the program
proceeds to start processing characters for the terminal window. With
the parameters defaulting to zero, certain calculations come out wrong,
leading the program to attempt to scroll the buffer when it shouldn't,
and thus follows the crash.
Instead, force the call to terminal_resize_cells() during the init, with
some dummy defaults, to ensure the parameters are always non-zero.

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:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120249.html
and the thread I hijacked to get some answers:

which culminated to the conclusion:
https://lists.freedesktop.org/archives/mesa-dev/2016-June/120955.html
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.

Previously weston_config_section_get_uint was serving dual purpose for
parsing both unsigned decimal integer values (ids, counts, seconds,
etc.) and hexadecimal values (colors), by relying on strtoul's
auto-detection mechanism.
However, this usage is unable to catch certain kinds of error
conditions, such as specifying a negative number where an unsigned
should be used. And for colors in particular, it would misparse hex
values if the leading 0x was omitted. E.g. "background-color=99999999"
would render a near-black background (effectively 0x05f5e0ff) instead of
medium grey, and "background-color=ffffffff" would be treated as an
error rather than white. "background-color=0x01234567",
"background-color=01234567", and "background-color=1234567" each
resulted in the value being parsed as hexadecimal, octal, and decimal
respectively, resulting in colors 0x01234567, 0x00053977, and 0x0012d687
being displayed.
This new routine forces hexadecimal to be used in all cases when parsing
color values, so "0x01234567" and "01234567" result in the same color
value, "99999999" is grey, and "ffffffff" is white. It also requires
exactly 8 or 10 digits (other lengths likely indicate typos), or the
value "0" (black).

This is required, because when a frame callback arrives, the just

complete, before the previous buffer is release. However, we want to be

necessary.
