So far scene-graph building and plane assignment happened within a single
loop. In the future we want to be able to optimize the scene-graph
before assigning, thus split up the loop into two steps.
No behavioral changes intended.

This changeset adds three variants of the U.S. Dvorak layout to the
table that is used to map a keyboard ID in the RDP backend to an Xkb
configuration. This makes it possible to have these variants
propagated seamlessly from an RDP client into the Wayland compositor.
As the backend-rdp module requires at least version 2.3.0 of the
FreeRDP library to build, the symbols for these variants is already
present in include/freerdp/locale/keyboard.h, included by rdp.h here,
and in libfreerdp/locale/xkb_layout_ids.c which translate the selected
layout in Xkb into the keyboard ID sent over the wire for the RDP
protocol.

We've been clobbering non-solid buffers with solid buffer attachment in
situations where we override the real buffer with a placeholder.
If the reason (punch hole, censor) that led to the placeholder is no
longer in effect, and new buffer is attached, we won't render what we should.
Instead, let's not attach anything for the paint node draw_solid case, and
allow gl_buffer_state be NULL when the real buffer is solid. gl_buffer_state
can then always be the correct state for the real buffer, even if we don't
use it.

Previously, inverse_evaluate_lut1d was called 3 * len^3 times. Now it is
called only 3 * len times with the help of pre-computed arrays for red
and green channels. Blue channel does not need an array, because there
were no redundant computations. This is a significant win.
Also, allocate a temporary array rgb_in, so cmsDoTransform() can be
called in batches of len triplets. This seemed to be not that big win. I
tried running cmsDoTransform() over len^2 triplets, but that did not
seem to improve performance.
The test I used creates two 3D LUTs, hence two times for a single run.
My representative timing test results per one 3D LUT:
- before: 16 ms and 19 ms
- after: 7 ms and 10 ms
The measurements were done with this patch:
static bool
xform_to_shaper_plus_3dlut(struct weston_color_transform *xform_base,
uint32_t len_shaper, float *shaper,
uint32_t len_lut3d, float *lut3d)
{
struct cmlcms_color_transform *xform = to_cmlcms_xform(xform_base);
struct weston_compositor *compositor = xform_base->cm->compositor;
bool ret;
+ struct timespec begin, end;
+ unsigned i;
- ret = build_shaper(xform->lcms_ctx, xform->cmap_3dlut,
+ clock_gettime(CLOCK_MONOTONIC, &begin);
+ for (i = 0; i < 100; i++)
+ ret = build_shaper(xform->lcms_ctx, xform->cmap_3dlut,
len_shaper, shaper);
if (!ret)
return false;
- ret = build_3d_lut(compositor, xform->cmap_3dlut,
+ for (i = 0; i < 100; i++)
+ ret = build_3d_lut(compositor, xform->cmap_3dlut,
len_shaper, shaper, len_lut3d, lut3d);
if (!ret)
return false;
+ clock_gettime(CLOCK_MONOTONIC, &end);
+ fprintf(stderr, "%s: %" PRId64 " ms\n", __func__, timespec_sub_to_msec(&end, &begin));
return true;
}

This removes the API impedance mismatch between
weston_color_curve_sample() and weston_color_curve_to_3x1D_LUT() that

Future development will need to evaluate pipelines with curves and
matrices. Such pipelines naturally operate on vec3, as matrices cannot
be operated one channel at a time. Make weston_color_curve_sample()
operate on arrays of vec3.
Its currently only caller, weston_color_curve_to_3x1D_LUT(), is modified
to employ a temporary array for the API impedance mismatch. This
workaround will be removed later as weston_color_curve_to_3x1D_LUT()
itself will be converted to operate on vec3 arrays.
weston_v3f_array_to_planar() documentation was generated with AI.
weston_color_curve_sample() is restructured a little bit, attempting to
make it simpler to read.
color-operations.h gets the #includes needed to make it self-standing.

We can handle the mirroring for negative input without conditional this
way. Maybe it's faster, maybe it's not, but I like this style better.
In color-operations we need only one call to the elementary function
rather than two. This helps a lot with code clarity, when we get a vec3
at a time to handle in the future, doing three trivial calls instead of
six with an if-else hassle.
fragment.glsl sheds one layer of function wrapping, which is nice.

Instead of clipping the visible region to the output, clip the entire
region to the output first and save that, then create the visible region
from that.
Now we have both the clipped and visible view regions that the backends
may want to do plane assignment stored in paint nodes, so we can save
some duplicate math.

Now that we use single pixel buffer, we need to be careful to only use
scale of 1, as other scales are supposed to generate an INVALID_SIZE

of the scale).
Right now a bad scale just breaks background repaints, but in the future
we'll properly validate scale, which would cause the shell client to
be disconnected.
