The error handling for the function that writes the encoded frame on
the disk was bogus, always assuming the buffer supplied to the encoder
was too small. That would cause a bigger buffer to be allocated and
another attempt to encode the frame was done. In the case of a failure
to write to disk (due to ENOSPC, for instance) that would cause an
endless loop.

The zoom translation is just a scale and a translate. The translation
is calculated based on the coordinates of the pointer which are in
global space. Previously the calculated translation was transformed by
the output transformation so that when the zoom transform is applied
after the output transform then it will be correct. However if we just
apply the zoom transformation first then we get the same result
without the zoom code having to be aware of the output transformation.
This also fixes weston_output_transform_coordinate which was applying
the output and zoom transforms in the wrong order.

If the scale for the cursor surface doesn't match that of the output
then we shouldn't use the cursor overlay because otherwise it will be
drawn at the wrong size. This problem is particularly noticable with
multiple pointers because it randomly alternates between drawing one
cursor or the other at a larger size depending on which one gets put
in the cursor overlay.
When converting output-relative coordinates (such as from an input
event) to global coordinates it now takes into account the zoom
transform. Previously this would only work for the primary pointer
because the transform doesn't affect the primary pointer position due
to that way zoom follows the mouse. Touch events and multiple pointers
were not working correctly.

send_configure was originally modelled after
wl_shell_surface::send_configure, which takes these arguments. However,
the X WM and xdg_surface::configure variants don't use these arguments.
We already store the resize edges for a surface while it's being
resized, so just use the saved state in the wl_shell_surface variant.
There is no need to unset WAYLAND_DISPLAY and WAYLAND_SOCKET when screen-share
launches the fullscreen shell server. This was done originally in case the
launched server decided to use the wayland backend based on the presence of
these. However, we pass a command line argument telling it to use the RDP
backend, which overrides the automatic backend selection based on the
environment.
Keeping these environment variables allows the launched fullscreen shell server
to know the original server's display name, which it may need in order to show
a configuration UI.

In order to apply the zoom transformation to the output matrix, Weston was
doing the following:
• Create a temporary matrix to hold the translation
• Invert the translation matrix using weston_matrix_invert into
another temporary matrix
• Scale that matrix by the scale factor
• Multiply the current matrix with the temporary matrix
Using weston_matrix_invert to invert a translation matrix is over the top.
Instead we can just negate the values we pass to weston_matrix_translate.
Matrix multiplication is associative so creating a temporary matrix to hold the
scale and translation transform should be equivalent to just applying them
directly to the output matrix.
Make sure that we don't map a device to an invalid output pointer and
intead remap devices when an output is created.
v2: fix the error with libinput too.
If the output a touchscreen is paired to is unplugged, events coming
from it should be ignored. Commit 17bccaed introduced logic for that
in evdev_flush_pending_damage(). However, the break statements it
introduced would cause the assertion after the switch statement to
fail.
That function has the odd behavior that goto's are used to skip the
assertion after the switch statement and jump to the hunk of code that
marks the event as processed. Only in the case where the event type has
an invalid value the assertion should trigger. So this patch fixes the
problem by moving the assertion into the default case of the switch
and replacing the goto statements with break ones.
https://bugs.freedesktop.org/show_bug.cgi?id=73950
Commit 17bccaed intended to make the events coming from a touchscreen
paired with an unplugged output to be discarded, while an unpaired one
would just choose a different output. However, the logic was inverted
causing the opposite to happen.
Later in commit 161c6c56, the default behavior was changed to map an
output to a default output if the one specified via udev is not
present. This change is reverted by this patch.
v2: undo the change from commit 161c6c56.

The rationale here is, that this line would create an instance of
gl_renderer_interface in every compilation unit that included
gl-renderer.h. This is not necessary, and it can actually be harmful by
masking the real exported gl_renderer_interface symbol, if you added
another compilation unit to gl-renderer.so, causing a runtime failure in
loading it.
gl-renderer.c already creates the exported symbol.

If an input device wants to map to an output that does not
exist, then just map it to the first output.
Also, if a device is mapped to an output that gets unplugged then
it gets default mapped to the first output in the output destroy
listener. However, the original output destroy listener needs to
be removed before adding the new listener for the first output,
otherwise the list gets corrupted.
Later if the other output is plugged back in, we remap the device
to it. In that case, we should remove the destroy listener for
the first output.

Commit 58e15865 changed the parameters for udev_get_seat_by_name() to
receive a struct udev_input. However, when this gets called from

The position for the slide animation was calculated assuming the value
of the spring was always between 0.0 and 1.0. Commit 3a869019 broke
that assumption, and the result was that the panel would be positioned
at an invisible part of screen. Since there would be no output repaints
scheduled, the result of the animation would only be seen if something
else triggered a repaint (such as a mouse cursor movement).
This patch changes the values for the slide animation's spring to range
between 0.0 and 1.0, thus fixing the position of the panel and the lack
of scheduled repaints problem.

All the animations override at least one parameter of the spring that
is set during the creation of the animation. Some need to do the whole
setup again.
This patch changes the initialization of a view animation to a three
step process. First, the animation is created. Then the caller sets up
the spring and calls weston_view_animation_run() to apply the effect of
the animation for the first animation frame.
It takes the stride in bytes, not pixels. The bug was hidden when using
va intel-driver 1.2.1 because it would ignore the stride from user and
set the surface state in a wrong way.

through and made sure that config.h is included first whenever system
headers are included.
The config.h header should be included before any system headers, failing
to do this can result in the wrong type sizes being defined on certain
systems, e.g. off_t from sys/types.h

If the client attaches a new SHM buffer with a different format from a
previous one then we ought to trigger a full upload so that GL can
allocate a new texture. Otherwise Weston would technically be doing
invalid operations because it would call glTexSubImage2D with a
different format from the one specified in glTexImage2D. Presumably it
would also mean GL would have to convert the buffer as it copies the
sub-region in which isn't ideal.
This patch makes it decide the GL format when the buffer is attached
instead of when processing the damage and it will set
needs_full_upload if it is different from what it used before.
When the alpha channel of a surface is changed and the surface
refreshed, pixman renderer will now apply a mask corresponding
to the alpha channel value.
This allows visual effects like shell fade in, shell fade out,
window switching, to work when using pixman renderer.

Previously when uploading SHM data we would initialise the texture
with glTexImage2D and NULL data when the buffer is attached. Then if
the GL_EXT_unpack_subimage extension is available we would always use
glTexSubImage2D to upload the data. The problem with that is that the
first glTexImage2D was always setting the internal format to
GL_BGRA_EXT and then if a 16-bit texture is used we would later call
glTexSubImage2D with a data format of GL_RGBA. Under GLES2 the
internal format must always match the data format so this is
technically invalid.
This patch makes it so that it always calls glTexImage2D when flushing
the damage for the first time. That way it will use the right internal
format and we don't need to call glTexImage2D with NULL data.

Let's make the source and destination size rules consistent: neither can
have zero, {-1, -1} disables it, and other negatives are not allowed.
The sanity of allowing zero sized source rectangle as debatable. Now the
minimum becomes 1/256x1/256, and with output_scale the actual samples
may be even smaller. That should be enough.
On not allowed values, raise a protocol error. This should help catch
bugs in clients that accidentally send garbage values.
The old wl_viewport.set request remains the same, and can still produce
zero sized source rectangle.

This adds a plugin called screen-share.so. If the screen-share.so module
is imported, it will add the CTRL+ALT+s keybinding to start a screen
sharing session. If you press CTRL+ALT+S, weston will spawn another copy
of weston, this time with the RDP backend, and mirrors the current screen
to it and adds any seats from RDP as aditional seats. The current screen
is defined as the one with the mouse pointer. Currently the CTRL+ALT+s
keybinding is hardcoded as the only way to activate screen sharing. If, at
some point, shells want more control over the screen sharing process, the
API's should be easy to update and export to make this possible.
For security, the command and path to weston is currently hard-coded. It
would not take much aditional code to make this configurable or to allow a
shell to launch other screen-sharing programs. However, handling those
security issues is outside the scope of this patch so it is hard-coded for
now.

This patch adds an option to the RDP compositor to disable

is that if an incoming RDP peer suggests a resolution that is

that behaviour. If the flag is set, the new behaviour is that the
RDP peer will be instructed to resize to the size of the desktop.
