Blend files with compositor node trees saves in 4.2 do not work in older
version. This is because 4.2 removed the chunk size property of the node
tree, so it is set to zero, which is invalid in older versions. To fix
this, we add it again as a deprecated DNA member, and set it to default
value upon write.

Implements the GPv2 onion skinning functionality.
There are no functional changes exept for the `use_ghosts_always`
option, which has been removed. This was used to show onion
skinning in the final render.

Move the public functions from the editors/object (`ED_object.hh`)
header to the `blender::ed::object` namespace, and move all of the
implementation files to the namespace too. This provides better code
completion, makes it easier to use other C++ code, removes unnecessary
redundancy and verbosity from local uses of public functions, and more
cleanly separates different modules.
See the diff in `ED_object.hh` for the main renaming changes.

Store RNG on per thread data, instead of the effector itself which may
be used by multiple objects evaluated in different threads.
This has been causing the blendfile_versioning test to fail randomly.
Thanks Ray and Aras for helping track this down.

Addresses two improvements to `Snap to Grid` as suggested in #73993:
- Make 'Absolute Grid Snapping' a new Snap Mode
- Snap to Grid in Non-Side View performed at ground level
Implementation details:
- Snap to Grid has no cursor symbol, unless we are in `Set Snap Base`
mode. Similar to the previous 'Absolute Grid Snap' behavior.
- In Non-Side view, Snap to Grid is performed at ground level.
- If `Snap Base` is `Closest`, Snap to Grid uses the transform pivot
point instead. Similar to the previous 'Absolute Grid Snap' behavior.
- The "Absolute Grid Snap" option has been removed.

This patch refactors the backdrop offset to be stored as a float instead
of an int and to be stored in the image runtime structure instead of the
image itself.

Now that all relevant code is C++, the indirection from the C struct
`GPUVertBuf` to the C++ `blender::gpu::VertBuf` class just adds
complexity and necessitates a wrapper API, making more cleanups like
use of RAII or other C++ types more difficult.
This commit replaces the C wrapper structs with direct use of the
vertex and index buffer base classes. In C++ we can choose which parts
of a class are private, so we don't risk exposing too many
implementation details here.

Compositor: Make Hue Correct node wrap
This patch makes the Hue Correct node as well as the Hue Correct VSE
modifiers to wrap, such that no discontinuities occur for the red hue.
Since it now wraps, the default curve preset now exempts the last point
of the curve.
A new CUMA_USE_WRAPPING flag was added to specify wrapping for curve
maps. The implementation works by adding two virtual points before and
after the terminal points in the curve map, such that their handles
match, and would then produce a continues curve.
This is a breaking change, since existing curves were also adjusted
using versioning. However, the change will not be significant, since in
most realistic cases, the terminal points will be close to each other,
and even with wrapping, the connection will be very sharp, almost
matching the old behavior.

Enables operators that uses `WM_operator_props_dialog_popup`
or `redo` popup to use layout panels.
Other popups would likely also support layout panels, only
they need to set its dummy panel with `UI_popup_dummy_panel_set`.
Popups don't normally use `Panel`, but that's the type that stores the
layout panel states. Therefore, to use layout panels in a popup, one
currently needs to create a dummy panel whose purpose is to store the
layout panel states for as long as the popup is open.
Alternatively, we could potentially also store the layout panel states
somewhere else in the future for popups, but that might be a more involved
change for now.
See #119519 for an example script that uses layout panels in a popup.

Allow the user to scale shadow-map resolution per-light.
Adapt the PCF scale based on shadow-map to pixel footprint ratio,
since we can no longer assume that higher LODs don't need filtering.
This allows using much lower shadow resolutions, which can yield
quite significant performance improvements, with relatively little
perceptual quality loss (at the cost of softening shadow edges).
The per-light resolution scale is a literal scale, so for example 0.5
means half the resolution. The Scene Simplify Shadows setting has
been updated to match this behavior.

Since [0] some comments referencing UI_MAX_NAME_STR were incorrect.
Also correct buffer size for preview_id in uiTemplatePreview so newly
created names are guarantee to be the correct size.
[0]: a180314ac5
The list identifier includes the class name and an list_id,
see: WM_uilisttype_to_full_list_id
This requires using UI_MAX_NAME_STR (as noted in doc-string).
This uses Spherical Harmonics to store the indirect lighting and
distant lighting visibility.
We can then reuse this information for each closure which divide
the cost of it by 2 or 3 in many cases, doing the scanning once.
The storage cost is higher than previous method, so we split the
resolution scaling to be independant of raytracing.
The spatial filtering has been split to its own pass for performance
reason. Upsampling now only uses 4 bilinearly interpolated samples
(instead of 9) using bilateral weights to avoid bleeding.
This also add a missing dot product (which soften the lighting
around corners) and fixes the blocky artifacts seen at lower
resolution.

For historical reasons, the `multi_input_socket_index` was actually reversed

adds a comment. This new name makes it less confusing that the id is reversed.

Experimental flag for "Extensions Development Utilities" that can be

Similar to the recently introduced `Solver` enum. This is just friendlier
and doesn't require including `DNA_node_types.h` in the geometry
module header. There's no strong benefit to declaring these enums in
DNA in practice.
This adds a "Solver" option to the geo boolean node, with the options
Exact and Float.
The current geo boolean node only uses the Exact solver.
This adds the ability to use the faster original floating point boolean solver.
The float solver has issues with coplanar and other coincident geometry,
but is generally much faster than the Exact solver, and users have asked
for this option (which is available in the Boolean Modifier and edit mode
boolean tool).
Like the modifier, the Float solver needs to convert the Mesh to BMesh,
do the operation, and then convert back to Mesh. It also has to do it
iteratively if more than two operands are supplied.
This is the first of a planned series of commits that will add a
new exact boolean solver, based on the Ember paper, as a solver option.
Ember will be much faster than the current exact solver, but may still not
be as fast as float, and also will not handle some non-volume-enclosing
inputs as well as Float, so it is likely that the Float solver will always remain.
We may eventually retire the old Exact Solver, however.
This commit also prepares for more sensible code in the future by
changing the internal enum names for the solvers to better reflect the
algorithms used: Fast -> Float, and Exact -> Mesh_Arr (which means
"Mesh Arrangments, the name of the paper upon which the current
exact solver is based).

This fixes an issue where the `use_masks` functions on layers
and groups returned the wrong value.
The issue was that the root group doesn't have this flag set
which then propagates to all the layers and groups.
To fix this we invert the `GP_LAYER_TREE_NODE_USE_MASKS` flag (now called `GP_LAYER_TREE_NODE_HIDE_MASKS`).
The API still uses the `use_masks` function.
Layer masks were partly already there. This PR completes the implementation and expose them through the UI.
This also adds three operators to:
- add a layer mask
- remove a layer mask
- reorder layer masks
Note: These are not used by the renderer yet. Will be done in a following PR.

Lines in the history never change, each input line is added to the
end (unless it is a duplicate of the last item).
A new history_index member keeps track of where the up/down arrows have
moved in the history.
Preserved the previous down-arrow behavior of going to the item after
the one that was copied, this is useful in Python for re-entering a
multi-line block.

"Own" (the adjective) cannot be used on its own. It should be combined
with something like "its own", "our own", "her own", or "the object's own".
It also isn't used separately to mean something like "separate".
Also, "its own" is correct instead of "it's own" which is a misues of the verb.
