Fix T73505 EEVEE: Group output node sockets default value not working

This just cleanup the code and apply the expand to group output nodes.

Revert "COW: Edit Mesh: Do not copy the looptris pointer"

Fix T74984: Crash opening specific production files

More detailed symptoms: there was no curve cache created for an object
which was used by draw manager.

A bit tricky situation, which involves collection instances and their
proxies.

The root of the problem in the dependency graph was that instanced
collections visibility was not updated when object is requested with
different visibility. So what was happening is that one of the objects
was pulled as an indirect dependency of something invisible, so it
built instanced collections as if the instancer is invisible. After
that the same object was built as visible. Before this fix this was
only update object flags, the instanced collections still believed they
are invisible. Since there is no path via relations which would connect
visible object with instanced objects the visibility flush which is
happening during graph finalization did not "fix" the visibility flags.

This change makes it so instanced collections are updating their
visibility when their instancer's visibility is changing to truth.
This is similar to how collections will accumulate their visibility
when same collection is used from multiple ones with different
visibility.

However, this alone wasn't enough to get crash fixed. This marked
collections as visible, but the geometry component of the curve object
was still considering self as invisible.

This is something tricky, since the code which is responsible for this
issue was added as an optimization in afb4da6650d. This looks like like
an oversight in that commit since it's rather weird that ID node's
flag would depend on construction order (in "normal" object builder the
ID node's directly_visible flag is initialized to object's visibility).
So it seems logical to get this part of code in sync between "regular"
and "accumulative" object builder.

And last but not least the naming is_directly_visible is old and does
not really represent what it actually mans now: a more correct name
would be "will be used by the draw manager".

Fix T74782: WorkBench TAA Artifacts During Painting/Drawing

When the TAA is finished the screen can still be redrawn by other
operations without the TAA needs to be reset.
If that happened the TAA did add a blank sample to the result.

This patch will add an early exit in the case TAA was finished. Note
that there are still some cases still not working. The overlay engine
can in certain circumstances draw directly into the default_fb what can
lead to render artifacts.

Bump subversion for previous theme additions

UI: Theme options for checkerboard pattern colors and size

This patch adds ability to set up colors and size of background
(transparency) checkerboard pattern in viewport and 2d editors. No new
backgrounds, only changing colors in existing ones.

This is not the background of the viewport, it is a transparency
checkerboard that is turned on only in render mode, when the
transparency mode is on. And also in 2D-editors, (image, sequencer,
etc).

Change solidify's material offset in complex mode to conform with simple mode

this patch will change the behaviour of the material offset in complex mode to fit simple mode output.
Previously in complex mode this would offset the material of the enire shell,
because when you read the tooltip it says material for new generated geometry.
In complex mode everything is new generated geometry though.
In simple mode on the other hand, this would give you a way to only change the inside faces
material. There may be cases in large modifier stacks where material offset like it is implemented
currently in complex mode may be useful, but it is much more useful in the way it is implemented
by simple mode.

Depsgraph: Driver Relations, skip finding possible relation with one driver

Fix T74586: Image Editor Uses Invalid Display Channels

When using the image editor the display channels attribute can become
invalid when selecting another image/buffer. This patch will check what
display channels are valid and when an invalid channel is selected it
will fall back to the color channel.

To de-duplicate the code it also introduces a
`ED_space_image_get_display_channel_mask` function that will determine
the valid bitflags for the display channel of a given `ImBuf`.

Sound: Fix asymmetrical mutex lock/unlock logic

Started to happen after recent fix for T72632.

Was caused by runtime fields backup doing an early exit in the case the
given ID was never expanded by the Copy-on-Write mechanism, but it was
not done int the backup restore function (since it was not possible to
know "locally").

Now both init() and restore() will do an early exit when the ID had
nothing to be backed up.

Fix T74964: Stereo Viewport Rendering Not Working

On some platforms the stereo viewport rendering was not working. The
issue was that the fragment shader and vertex shaded didn't match. Some
platforms will remove the non-matching in/out parameters and blender
needs to provide only the optimal set of parameters. Other platform
still want to receive data for the parameters that aren't used.

This fix uses the correct vertex shader that matches the fragment shader
making both platforms render the same result.
