99527e6b92 input: Introduce weston_key_event struct
Rather than passing a time stamp, key, key state and key event state
use a weston_key_event struct to pass by all that using it.

This would allow in further patches to attach additional information
like a flow id used by Perfetto debug annotations for input events.

This patch has no functional change as it is now.

All the callees will just will extract the required information out of
struct weston_key_event.

b88695e3d5 compositor: Update transform in weston_coord global converters
I added these assert()s and have regretted it ever since. I'm sorry.

They've led to a bunch of places that just cargo-cult call
weston_view_update_transform() immediately after dirtying the transform,
as well as a lot of very carefully chosen places that took far too long to
sort out.

weston_view_update_transform() is an immediate return if the transform
isn't dirty, so let's just update them here instead of making everyone
think really hard about when to call weston_view_update_transform().

This should let us remove a few transform updates, and should
make the weston_coord functions a little easier to use.

Unused.

This was using the old way of getting screenshots: hooking to
weston_output::frame_signal and calling weston_renderer::read_pixels().
This old way stalled Weston until the GPU work was complete, and
supported only wl_shm buffers.

32d0bd3d0e compositor: add grayscale output color effect
This adds a new output color effect: grayscale. It takes RGB color as
input and computes a gray pixel color using the luminance formula for
linear sRGB:

Y = 0.2126 * R + 0.7152 * G + 0.0722 * B

Just like the other color effects we have, this only works for sRGB and
are not enabled when color-management is on.

Note: although the technique is designed to be applied in linear, it's
costly to convert to linear and then back to electrical. As doing the
conversion in electrical still gives a reasonable result, we do it this
way. When we add support for color effects with color-management on,
we'll apply the effect in linear.

2e61633b32 libweston: Use a string for storing surface label
This is an alternative to using set_label_func to avoid using get_label()
callback. get_label() is inconvenient to set up and to call. It incurs
the cost of creating the string every time it is needed. During
debug logging, the string is needed much more often than it changes.

The new label field simply stores the string, making it easy and cheap
to use. As the trade-off, components that set the label string must
re-create the string when it changes, whether it is needed or not.

For the migration to the new label field, get_label_member callback is
used. It will be deleted once the migration is done.

cfecdce2f5 libweston: give weston_views a simple name

address "%p" (not human-readable) and very likely assumption that a

a209e13526 libweston: give weston_surfaces a simple name
So far we have had two ways of identifying a weston_surface: by its
memory address "%p", and by its get_label function. The memory address
is not human-friendly and can get recycled. get_label() is not unique,
and in some cases it is client-controllable.

Oh, we also have the protocol object ID, but that does not exist for
internally created weston_surfaces.

We also have weston_surface::s_id, damage_track_id and flow_id. These
are used by some Perfetto instrumentation. s_id comes from a
compositor-wide counter rather than per-client counter, the others are
probably not what I'm looking for.

None of these are really nice for trace and debug prints for identifying
surfaces for human reading. Therefore, let's add one more ID, and with
it, a nice name for each surface.

is to associate an ID with each client. The ID is much better suited for

desired for compositor forked clients like Xwayland or shell helpers.

e4be014f93 compositor: Add an explicit latch point
Latch is the moment when the compositor considers updates for an upcoming
redraw. Nothing that takes place after an output latches for repaint can
change what will be repainted.

This needs a more explicit treatment now that upcoming transactional
protocols require things to happen immediately after the latch (ie:
when it's too late to change the upcoming render).

Add an explicit latch point, a signal to tap for testing, and some asserts
to make sure nothing can violate the inevitability of the current render
state.

Note that currently latch is tied to repaint such that we only claim to
have latched when a repaint will happen. In a future commit this will lead
to forcing the repaint loop to fire without damage when the fifo protocol
needs something to happen after a latch. This could be an area for
future improvement.

b44cf1b6af animation: Change how we seed the initial time
With the addition of the weston_output_set_ready() call, the shell fade
animation is now started during the very first repaint. The first repaint
doesn't have an accurate frame_time for the previous repaint, as none has
occurred yet.

Since we set the time base for an animation based on the output's frame
time the second time the animation is run, we end up setting the shell fade
start time to 0, and the first real repaint advances the timer to the real
time, generating a warning and truncating the animation.

Instead of tracking the number of animation frames, let's just continue to
reset the time base until we finally get a non-zero time.
