86168b945c window-stream-source: Draw into DMA buffer image
Much like monitor streaming, implement window streaming by
making the window actor draw itself with a paint context
that used the passed framebuffer.

Now that all MetaScreenCastStreamSrc subclasses implement
blit_to_framebuffer, remove the conditional check from
meta_screen_cast_stream_src_blit_to_framebuffer().

Add the vfunc override that actually consume the new Cogl API. Every
view that fits into the logical monitor is rendered.

548073ec27 screen-cast-stream-src: Support DMA buffer sharing
Implement PipeWire's add_buffer and remove buffer, try and export
a DMA buffer first and, on failure, fallback to memfd.

When DMA buffers are successfully created and shared, blit the
framebuffer contents when drawing instead of downloading the pixels.

d366fb335d renderer-native: Implement DMA buffer creation
Create a new gbm_bo using the same given geometry, and export the new
bo's DMA buffer fd. The new bo lives as long as necessary to be used,
and reused, by PipeWire.

Unfortunately, PipeWire doesn't support modifiers properly, so use the
linear format for now. For now, a hardcoded format of DRM_FORMAT_XRGB8888
is set, so we don't need to negotiate the format with PipeWire early.

3881c1f952 cogl/context: Add cogl_renderer_create_dma_buf() and family
This is a winsys-specific API that allows exporting a DMA buffer fd.
The CoglDmaBufHandle structure allows passing the ownership of the
DMA buffer to whoever is using it, so the winsys doesn't need to

038a3170bf cogl/framebuffer: Add cogl_framebuffer_flush
In future patches, we'll create additional CoglFramebuffers that
will be shared via DMA-Buf with PipeWire. When recording frames,
we'll blit the current onscreen framebuffer into the shared one.

However, that presents a problem: cogl_framebuffer_blit() mimics
glBlitFramebuffer() semantics, and doesn't do an implicit flush
of the GPU command stream. As a consequence, clients may receive
unblitted or incomplete framebuffers.

We could use cogl_framebuffer_finish() to ensure the commands were
submitted to the GPU, but it is too harsh -- it blocks the CPU
completely until the commands are finished!

Add cogl_framebuffer_flush(), which ensures the command stream is
submitted to the GPU without blocking the CPU. Even though we don't
use the framebuffer specifically, it may be useful in the future
for e.g. a potential Vulkan backend to have access to the framebuffer.

987ce5bec0 cursor-renderer/native: Implement scaled/transformed hardware cursors
If the cursor sprite does not match the scale factor or transformation
of the monintor, we currently fall back to a software cursor, causing
redraws of the shell. This commit implements scaling and transforming
of the cursor sprite, so we can use it with hardware planes, too.

This commit does the following steps:

1. Make sure we reupload the cursor image if the cursor is over
a logical monitor not matching the scale or transform from the previous
update.
2. Before upload to the hardware plane, scale and transform the cursor
image if possible and necessary.
3. Make sure we always use the hardware cursor if possible (only fall
back to software/OGL cursor if it is visible on multiple logical monitors
with differet scales/transforms).
4. Transform or scale the cursor coordinates if necessary.

88bb24f66e backends/native: Shuffle udev client initialization in MetaSeatNative
This may be used indirectly before creation as we dispatch libinput events
right after creation (to let input devices be known), so those device
additions would trigger the touch-mode checks.

Creating it in advance results in checks being correctly performed, although
redundantly.

9fa56176fd monitor-manager-xrandr: Don't try to disable disabled CRTC
When applying a configuration to XRANDR, we first disable CRTCs that
happen to extend outside of the to-be X11 screen size. While doing so,
we fail to actually check whether the CRTC is active or not, meaning
we'll try to query the content of the CRTC configuration even though it
has none, leading to a NULL pointer dereference.

Fix this by simply ignoring non-configured CRTCs.

159c83b914 clutter: Move redraw clip management to views
The stage window handled the redraw clip in a global manner; this would
interfere if we want to paint views individually as it'd mean
intersecting views (i.e. mirrored monitors) would loose the redraw clip
once the first view was painted. It also is awkward to have a global
state for something that is built up before redrawing, and only really
valid during paint, due to buffer damage history.

This commits removes all redraw clip management from the stage window,
moving it all into the stage views. When a redraw clip is added to the
stage, every affected view will get the same redraw clip added to it,
and eventually when painted, the stage window (ClutterStageCogl) will
retrieve the redraw clip for each view as it repaints them.

fe1ccea1e1 clutter: Pass redraw clip via paint context
Instead of users fetching it via `clutter_stage_get_redraw_clip()`, pass
it via the paint context. This is helpful as it is only valid during a

when there is no redraw clip (i.e. we're painting off-screen).

f3dcba27f5 clutter/cogl/stage: Simplify region transform code
Add a helper that scales and clamps a region, aimed to be used when
transforming between framebuffer coordinate space and view coordinate
spaces.

with the individual rects of a region to the helper, making the logic
where it's used much simpler.

86ccc28413 clutter/cogl/stage: Rename have_clip to is_full_redraw
The 'have_clip' variable has repeatedly confused me to meaning that
there is a clip. What it actually means is that the effective clip
covers the whole view; the 'redraw_clip == NULL' meaning full redraw is
an important implementation detail for the context, and makes the
intention of the variable unclear; especially since we will after a
couple of blocks will *always* have a clip, just that it covers the
whole view.

Rename the variable to 'is_full_redraw' and negate the meaning, aiming
to make things a lot more clear.

adcbc2aa5f clutter/cogl/stage: Use fb size for for fallback fb clip region
When calculating the fallback framebuffer clip region, which should be
the region in framebuffer coordinates, we didn't scale the view layout
with the view framebuffer scale, meaning for any other scale than 1,
we'd draw a too small region of the view. Fix this by just using the
size of the framebuffer directly, avoiding any scale dependent
calculation all together.

1c98f01a65 renderer-native: Draw stage separately per CRTC
Prior to this commit the stage was drawn separately for each logical
monitor. This allowed to draw different parts of the stage with
different transformations, e.g. with a different viewport to implement
HiDPI support.

Go even further and have one view per CRTC. This causes the stage to
e.g. draw two mirrored monitors twice, instead of using the same
framebuffer on both. This enables us to do two things: one is to support
tiled monitors and monitor mirroring using the EGLStreams backend; the
other is that it'll enable us to tie rendering directly to the CRTC it
will render for. It is also a requirement for rendering being affected
by CRTC state, such as gamma.

It'll be possible to still inhibit re-drawing of the same content
twice, but it should be implemented differently, so that it will still
be possible to implement features requiring the CRTC split.

fe42d56db3 crtc: Move configured state to separate struct
To make it more reliable to distinguish between values that are read
from the backend implementation (which is likely to be irrelevant for
anything but the backend implementation), split out those values (e.g.
layout).

This changes the meaning of what was MetaCrtc::rect, to a
MetaCrtcConfig::layout which is the layout the CRTC has in the global

0c55e87d8f cogl: reduce temporary allocations calculating redraw regions
When calculating regions, a lot of temporary allocations are created. For
the array of rects (which is often a short number of them) we can use
stack allocations up to 1 page (256 cairo_rectangle_int_t). For building
a region of rectangles, cairo and pixman are much faster if you have all
of the rectangles up front or else it mallocs quite a bit of temporary
memory.

If we re-use the cairo_rectangle_int_t array we've already allocated (and
preferably on the stack), we can delay the creation of regions until after
the tight loop.

Additionally, it requires fewer allocations to union two cairo_region_t
than to incrementally union the rectangles into the region.
