This services output capture tasks for the 'framebuffer' and 'full
framebuffer' pixel sources.
Both pixel sources come from the same source: the EGLSurface. The only
difference is the area. The EGLSurface contains the borders used for
output decorations, hence 'full framebuffer' is possible to capture.
We use GL_ANGLE_pack_reverse_row_order extension to make glReadPixels
return the image data in the layout we need for wl_shm buffers directly.
Without the extension we have to flip manually.
Another extension to the same effect is MESA_pack_invert, but this is
not specified for GL ES. It also uses a different token value, so it
cannot be directly substituted even if supported.

This services output capture tasks for the 'framebuffer' and 'blending'
pixel sources.
Just like the old screenshooting path, the 'framebuffer' pixel source is
the hardware buffer, whether a shadow is used or not. This may not be
the best for performance, but you do get the real framebuffer contents.
Maybe it's rgb565, or even less.
When the shadow buffer is used, I realized it is effectively the same as
the intermediate blending buffer in GL-renderer when color management is
used. Pixman-renderer does non-linear blending only, so the shadow
buffer is in the blending space. The shadow buffer is also always 8 bpc
regardless of the hardware framebuffer, so the read-back may be
different from the hardware framebuffer. Read-back from the shadow is
optimal for performance, but not what the hardware gets.
'full-framebuffer' source cannot yet be implemented, because backends do
not tell Pixman-renderer about the margins where the wayland-backend
blits the output decorations. The target "hardware" buffer handed to
pixman-renderer does not allow accessing the decorations area.

This implements the basics of the new screenshooting protocol. The
actual pixel operations will be implemented separately in the renderers
and DRM-backend.
See the previous commit "protocol: new screenshooter protocol" for why.
If DRM-backend needs more from weston_capture_task when it implements
writeback screenshooting, it will be easy to add user_data or expose
weston_capture_task::link for the backend to use. Those were not added
yet because it is uncertain what is actually needed.
The DRM-backend no-damage optimization requires special handling here as
well. See also 7f1a113c89 .

This is a completely new screenshooting protocol designed to support:
- color management testing by adding the "blending" source
- KMS testing by adding the "writeback" source
- output decorations testing by adding the "full_framebuffer" source
- proper buffer size negotiation instead of guessing from wl_output
- compositor chosen pixel format, primarily for "blending" source
- proper indication of screenshot failure
- dmabuf target buffers, linear only
This new protocol should be good enough to publish as a Weston public
extension. Hence install it.

Instead of basing this on simple checks, we can test the matrix. This

When we build up a matrix from a series of operations, it's very useful
to know if the combined operations still result in something that matches
a wl_output_transform.
This adds a function to test if a matrix leads to a standard output
transform, and returns the transform if it does.
Tests are provided that check if complex series of operations return
expected results - the weston_matrix_needs_filtering function is tested
at the same time.

If a transformation matrix causes a scale, a rotation not a multiple of 90
degrees or a non-integral translation then textures rendered with
it would benefit from bilinear filtering.
This test is done in a lazy fashion by examining elements of the matrix

If the view transform is dirty it might be incorrect. Also, we normally
set up the view transform matrix properly regardless of whether the

This introduces a few getters to retrieve the pending state from
libweston-desktop, now just libweston, and makes use of it,
specifically get_pending_maximized to avoid sending invalid
dimensions to the client in the particular use case
set_maximized/unset_fullscreen.
These pending state getters are useful to query/poke a not-applied
yet state, and could be useful where we don't have a buffer attached
where the client might be set-up as maximized, but internally libweston
hasn't yet applied that pending state.

Before this patch, when a new head is found its information is printed
first as "updated" and then as "found" in the log.
The reason is that drm_head_create() calls drm_head_update_info() which
printed the head as "changed". Then drm_head_create() itself prints it
as "found".
This fixes it to print only once as "found".

The first new event printed after the timeout expires will also include a

Signed-off-by: Marius Vlad <marius.vlad@collabora.com>
The motivations for this are:
- Y_INVERT is not used by most real-world clients.
weston-simple-dmabuf-egl and weston-simple-dmabuf-v4l are one only
known users. Thus this creates a special case just for these demo
clients.
- Some compositors (wlroots) have dropped support for DMA-BUF flags,
so the client no longer runs there.
- Dropping the flag allows compositors to use a KMS hardware plane to
display the buffer.
It keeps the same axis orientation we had in place where we had the
y-invert flag enabled by default, by doing a reflection about x-axis.
