Subject: [PATCH 01/20] cogl/dma-buf-handle: Pass more metadata to handle
constructor
Could be useful would one want to mmap the dmabuf and deal with its
content manually in CPU space.

Subject: [PATCH 02/20] clutter/stage-view: Add name property
Will be used for logging to identify what view a log entry concerns. For
the native and nested backend this is the name of the output the CRTC is
assigned to drive; for X11 it's just "X11 screen", and for the legacy
"X11 screen" emulation mode of the nested backend it's called "legacy
nested".

Subject: [PATCH 05/20] clutter/stage-view: Move fb viewport and projection
setting to here
The stage would fetch the front framebuffer and set the viewport and
projection matrix, but if we are going to more than one front buffer,
that won't work, so let the stage just pass the viewport and projection
matrix to the view and have the view deal with the framebuffer(s).

next time. Change the API used to reflect this.

shadow buffer to the onscreen.

Subject: [PATCH 10/20] clutter/stage-view: Simplify painting of offscreen
slightly
We will only ever have an "offscreen" if we're painting transformed in
some way, so the 'can_blit' checking is unnecessary. Remove it.

Subject: [PATCH 12/20] clutter/stage-cogl: Use buffer age when view monitor is
rotated
We failed to use the buffer age when monitors were rotated, as when they
are, we first composite to an offscreen framebuffer, then later again to
the onscreen. The buffer age checking happened on the offscreen, and an
offscreen being single buffered, they can't possible support buffer
ages.
Instead, move the buffer age check to check the actual onscreen
framebuffer. The offscreen to onscreen painting is still always full
frame, but that will be fixed in a later commit.

Subject: [PATCH 13/20] clutter/stage-view: Only paint redraw clip from
offscreen
The rest didn't change, so only actually paint the part of the offscreen
that was composited as part of the stage painting. In practice, this
means that, unless a shadow buffer is used, we now only paint the
damaged part of the stage, and copy the damage part of the offscreen to
the onscreen.

Subject: [PATCH 15/20] clutter/stage-view: Only blit the damage part of the
shadow buffer
This fixes the last "copy everything" paths when clutter doesn't
directly paint onto the onscreen framebuffer. It adds a new hook into
the stage view called before the swap buffer, as at this point, we have
the swap buffer damag regions ready, which corresponds to the regions we
must blit according to the damage reported to clutter.

Subject: [PATCH 16/20] clutter/stage-cogl: Extract damage history logic
Move the damage history tracking to a new ClutterDamageHistory helper
type. The aim is to be able to track damage history elsewhere without
reimplementing the data structure and tracking logic.

Subject: [PATCH 19/20] clutter/stage-view: Add tile based shadow damage
detection
Compare, tile by tile, whether actual damage actually changed any
pixels. While this requires mmap():ing DMA buffers and comparing their
content, we should only ever use shadow buffers when we're using the
software renderer, meaning mmap() is cheap as it doesn't involve any
downloading.
This works by making the shadow framebuffer double buffered, while
keeping track of damage history. When we're about to swap the onscreen
buffer, we compare what part of the posted damage actually changed,
records that into a damage history, then given the onscreen buffer age,
collect all actual damage for that age. The intersection of these tiles,
and the actual damage, is then used when blitting the shadow buffer to
the onscreen framebuffer.
Closes: https://gitlab.gnome.org/GNOME/mutter/-/issues/1157
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1237
(cherry picked from commit 068385df3a0cf545e5110378b59db56cbd1bdef3)

Subject: [PATCH 20/20] clutter/stage-cogl: Use view fb instead of onscreen fb
for debug-drawing
We need to use the framebuffer of the view instead of the onscreen
framebuffer when painting the damage region, otherwise the redraw clips
on rotated monitors won't be shown correctly.
https://gitlab.gnome.org/GNOME/mutter/-/merge_requests/1237
(cherry picked from commit 8e1bd64e05c3098fcce4f916f9e4468decb8f30c)
