Now that struct weston_renderbuffer is refcounted, hold a reference for
renderbuffers on the pixman_output_state::renderbuffer_list. This allows
backends to destroy the renderer output state and release renderbuffer
references in any order without running into an assert().
To avoid breaking resizing, We also have to drop the renderbuffer list
during pixman_renderer_resize_output(). The backends have to create new
renderbuffers afterwards.

In IVI, there are several displays connected to a SoC. These displays
are just driven by differential pairs (LVDS, FPD-Link, GMSL) and powered
centrally. To reduce power comsumption when user inactivity timeout
happended on the display, there is a need to cut down pixel clock from
SoC. Then, if any input events happend on the display, it should become
active again.
Currently, controlling the compositor outputs doesn't happen independently
but rather globally, and outputs repaints are based on the compositor state
This is necessary to have an API that can force the power state of an
output to off via DPMS mode while all other compositor outputs remain
unaffected.

When a view is destroyed then the views of subsurfaces remain until the view
list is rebuilt for the next repaint.
During that time view->parent_view contains an invalid pointer and weston will
crash when it tries to access the view.
This happens for a surface with subsurfaces with views on two different outputs
with the ivi-shell:
When the surface is destroyed then the destroy handler of the ivi-shell
(shell_handle_surface_destroy()) may be called first. It will (indirectly)
destroy the view of the main surface with weston_view_destroy().
Next the surface destroy handler of the subsurfaces
(subsurface_handle_parent_destroy() is called. It will unmap the first view of
the subsurface. Here weston_surface_assign_output() is called which tries to
find the output of the second view and accesses the now invalid
view->parent_view in the process.
There are probably other ways to trigger similar crashes.
To avoid this, clear view->parent_view when the parent view is destroyed.

Starting with commit 4cde507be6 "backend-drm: fix plane sorting" the
plane list will have a descending order of the planes rather than ascending.
This reversed order had the side-effect of exposing the fact that we
don't set-up a plane index when creating the drm_plane using the DRM
virtual API. Without settting a plane index for that drm_plane we
effectively overwrite the plane index which has the 0 (zero) entry.
This wasn't an issue before commit 4cde507be6 "backend-drm: fix
plane sorting" as it seems we never picked up that plane index as
being a suitable one due to the fact that those were assigned to primary
planes, but after that commit, the cursor plane will be one getting
the 0 (zero) plane index.
Finally, this would trip over because we attempt to place a (cursor)
view on a primary plane (where it would've normally be a cursor
plane) and we end up with no framebuffer ref.
This is fixed trivially by assigning a plane index, different than the
ones already created by create_spirtes().

converted to/from wl_fixed_t and other types.
We also have struct vec2d and struct weston_geometry which also
contain coordinate pairs.
Let's create a family of coordinate vector structures for coordinate
pairs and use it anywhere we sensibly can.
This has a few benefits - it helps remove intermediate conversion
between fixed/float/int types. It lets us roll the homogenous
coordinate normalization bits into helper functions instead of
needing them open coded throughout the source.
Possibly most importantly, it also allows us to do some compile time
validation of what coordinate space we're working in.

We are assuming that CRTC_GAMMA_LUT is pass-through, so better ensure it

Unfortunately, we have old drm_output_set_gamma() API that cms-static
and cms-colord plugins are using. To avoid trampling over them, do not
touch gamma after they did. Those plugins are deprecated, so there is no
reason to make set_gamma work through atomic.
drm_output_set_gamma() is called from weston_compositor_add_output()
through the output_created_signal. This is after drm_output_enable() and
before any KMS modeset or atomic commit on the CRTC. Therefore it is not
possible that there would be any KMS action in flight when
drm_output_set_gamma() is called, and so setting deprecated_gamma_is_set
should be non-racy - like setting CRTC_GAMMA_LUT itself.

GL-renderer keeps the pointer for the border image data for later use.
When we destroy our cairo_surface, that data gets freed. Therefore,
reset the pointer stored by GL-renderer too, to ensure use-after-free

This is not really necessary in this particular case, because the
renderer output is destroyed immediately after, so there is no chance of
UAF.
However, this is needed for code sharing purposes. Wayland-backend will
do exactly this when an output is resized. To share this code with

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

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 patch adds the essential LittleCMS color pipeline optimizations and
analysis that is necessary for extracting matrices from pipelines
correctly. When we can extract a matrix and 1D curve sets, we can use
those with GL-renderer without needing an inherently heavy and imprecise
3D LUT. This should improve color transformation precision and
performance when a 3D LUT is not necessary.
The core of the optimization and analysis is a custom plugin for
LittleCMS. The optimization step comprises of repeatedly merging
sequential matrices and sequential curve sets into one and eliminating
identity elements which may allow for more merging. The analysis step
takes the optimized LittleCMS pipeline and attempts to fit all of its
elements into the weston_color_transform model. If it fits, we have an
optimized color transformation and do not need a 3D LUT. If it does not

Restructing cmlcms_color_transform_create for readibility.
Also dropped zalloc() check in favor of xzalloc() as per the recent

Right now this function only creates a CMM pipeline and produces a 3D
LUT from it, but in the future it can produce other types of
transformations. The function is renamed to xform_realize_chain()
because it creates a chain of profiles, forms a multi-profile-transform
from them, and fits that into weston_color_transform.
The further refactoring supports the future changes, and attempts to
make the code more readable.
There is provision for easily adding more profiles into the chain.

Relax the types of color transformations categories where this function
can be used. Yes, it is only useful for BLEND_TO_OUTPUT, but that is for
the user of this function to take care of. This function always works as
named regardless. The only condition is that output_inv_eotf_vcgt has
been populated, so fill_in_curves() may as well assert that.
While at it, make the code a little more concise. The 'len' assertion
belongs in fill_in_curves() because that is where the problem would
appear if the assertion failed.

Rename cmslcms_fill_in_pre_curve to cmlcms_fill_in_output_inv_eotf_vcgt
due to importance what the function is fetching:
profile->output_inv_eotf_vcgt.

Eotf is the transfer function whose inverse must be used for
converting from output light-linear space to sink electrical space.

Add matrix in color.h
Matrix is used as an optimized method for
color mapping vs 3DLUT.
Nothing sets color mapping to matrix yet.

Add post-curve support in color.h.
Pre-curve and post-curve describe color pipeline components
in a single GL shader invocation.The GL shader is supposed
to match struct weston_color_transform exactly.
We have the following color pipeline:
shader A -> blending -> shader B -> KMS. Both A and B shaders
using the same source file :fragment.glsl.
Each shader has pre and post curve.
The typical color pipeline with 3DLUT:
Shader A: pre-curve identity->3DLUT->blending->post-curve identity
Shader B: pre-curve->3DLUT identity->post-curve identity->KMS
The typical color pipeline with matrix (in next commits):
Shader A: pre-curve->matrix->blending->post-curve identity
Shader B: pre-curve->matrix identity->post-curve identity->KMS
The pre-curve plays role of EOTF (shader A) or INV_EOTF
(shader B) becouse we are stiching the shaders.
We assume that someone in the future may use both pre-curve
and post-curve, for example, when it is not possible to combine
these curves into 3DLUT and we will do mapping elements based on
their location in ICC profile.

Currently the frame event gets lost: The touch focus is removed in the 'up'
event. So the focus is gone when the frame event arrives so it is never sent to
the clients.
To avoid this, keep the touch focus until the frame is handled.

Replace all the remaining weston_output::current_mode and borders[] uses
with the fb_size and the compositing area. The result is the same, but
we stop depending on weston_output, and border texture sizes which may
not be the same as border sizes.
This is more correct, semantically.

Do not use border texture size when we have the area stored. This
decouples border texture size further.
We also have buffer_height available directly from fb_size, so do not
reverse-engineer it.

Compute the border area from the framebuffer size and composited area
only.
Now the border textures can be freely sized while they will be stretched
to fill the respective border areas. In fact, this was already made use
of by having left/right image height=1 as special cases. Now all the
texture dimensions behave the same.
No change in behavior, the values are the same, just computed
differently.

This moves the identical code from draw_output_borders() and
output_get_border_damage() into a new shared function. Reduces code
duplication.
This is a pure refactoring, all the computations stay the same.

This step prepares to share the coordinate computations between
draw_output_borders() and output_get_border_damage(). The use of
weston_output is replaced with gl_output_state, so that when sharing the
code in a new function, it does not need a weston_output.
This stops the function from accessing output->current_mode and use the
gl-renderer tracked frambuffer size and compositing area instead. Not
using current_mode is a small step towards allowing gl-renderer to
render for other targets than an output.
No behavioral changes, all the values are still the same.
See the diagram in gl-renderer.h for the border areas.

We get rid of unnecessary GL-renderer output state destroy and create,
meaning we don't destroy and create an EGLSurface either.
