ViewLayer: Reduce object duplication syncing

During object duplication the syncing is temporarily disabled.
With {D15885} this isn't useful as when disabled the view_layer
is still accessed to locate bases. This can be improved by first
locating the source bases, then duplicate and sync and locate
the new bases.

This patch removes the resync forbid and improve the times
that resyncing actually must happen.

Fix T101394: Ensure all viewlayers on scene copy.

When a scene copy is called, all viewlayers are ensured before they are
copied. In case of multiple viewlayers, a viewlayer can be out of sync.
This triggers an assert in the BKE_view_layer_copy_data.

commit 68589a31ebfb79165f99a979357d237e5413e904 Author: Monique Dewanchand Date: Wed Sep 14 21:33:51 2022 +0200

ViewLayer: Lazy sync of scene data.

When a change happens which invalidates view layers the syncing will be postponed until the first usage.
This will improve importing or adding many objects in a single operation/script.

`BKE_view_layer_need_resync_tag` is used to tag the view layer to be out of sync. Before accessing
`BKE_view_layer_active_base_get`, `BKE_view_layer_active_object_get`, `BKE_view_layer_active_collection`
or `BKE_view_layer_object_bases` the caller should call `BKE_view_layer_synced_ensure`.

Having two functions ensures that partial syncing could be added as smaller patches in the future. Tagging a
view layer out of sync could be replaced with a partial sync. Eventually the number of full resyncs could be
reduced. After all tagging has been replaced with partial syncs the ensure_sync could be phased out.

This patch has been added to discuss the details and consequences of the current approach. For clarity
the call to BKE_view_layer_ensure_sync is placed close to the getters.
In the future this could be placed in more strategical places to reduce the number of calls or improve
performance. Finding those strategical places isn't that clear. When multiple operations are grouped
in a single script you might want to always check for resync.

Some areas found that can be improved. This list isn't complete.
These areas aren't addressed by this patch as these changes would be hard to detect to the reviewer.
The idea is to add changes to these areas as a separate patch. It might be that the initial commit would reduce
performance compared to master, but will be fixed by the additional patches.

**Object duplication**
During object duplication the syncing is temporarily disabled. With this patch this isn't useful as when disabled
the view_layer is accessed to locate bases. This can be improved by first locating the source bases, then duplicate
and sync and locate the new bases. Will be solved in a separate patch for clarity reasons ({D15886}).

**Object add**
`BKE_object_add` not only adds a new object, but also selects and activates the new base. This requires the
view_layer to be resynced. Some callers reverse the selection and activation (See `get_new_constraint_target`).
We should make the selection and activation optional. This would make it possible to add multiple objects
without having to resync per object.

**Postpone Activate Base**
Setting the basact is done in many locations. They follow a rule as after an action find the base and set
the basact. Finding the base could require a resync. The idea is to store in the view_layer the object which
base will be set in the basact during the next sync, reducing the times resyncing needs to happen.

Cleanup hardcoded render percentage to factor conversion

During revision of {D8952} one of the comments was to make a function that converts the render percentage to a factor. This to avoid code duplication. However the duplicated code was already all over the compositor code. So in order to avoid this code duplication for {D8952} I propose to first cleanup the duplicated code and build patch {D8952} based on this clean up.

The method that converts the render percentage to a factor is put in the CompositorContext. Why? The CompositorContext keeps DNA information like the renderdata. DNA, and thus the CompositorContext, keeps the size of the render resolution in percentage (user oriented). The compositor needs the size of the render resolution as a factor. So the CompositorContext seems like the obvious place to have this conversion method.

Why not in de NodeBase? The method could've been added to the nodebase, but I wanted to keep the nodebase as clean as possible and not put simple "conversion" methods into this base class. Also I didn't really like the call flow: you'd always have to get the renderdata size from the context and then convert.
Putting it in the CompositorContext avoids this extra invoke of a call.

Why not in the Converter? See nodebase. And the Converter seems more like a class for "structural" and complex node tree conversions. Not the simple conversions.

One fix for bug [#33785] compositor is (unnecessarily?) slow
Added additional buffers - new subtree - for groupnodes.
One needs to be aware of how groupnodes should be created.
Having translate & scale nodes, with the translate inside the groupnode and the scale node outside, causes artefacts.
Both should be inside or outside the groupnode. Same holds for other distort nodes.

 Apply patch [#33999] Wrapping mode for the "translate" compositing node

this patch enables the translate node to wrap around the image borders. This is especially needed if the translate node is not used to position elements on a layer but when it is used instead for seamless backgrounds like mountains or clouds that should be repeated over time (by animating the x/y values).

No trunk without docs! So here is my documentation: http://wiki.blender.org/index.php/User:Plasmasolutions/TranslateNodeExtension

The code is properly documented and should be easy to read and understand. When there are any problems or issues, please comment, I'll tackle them right away!

Greetings, Thomas Beck


 * optimized determination dependant areas

There are still some issues when scaling very small values (x=0.0001)

Patch by erwin94 [#34015] dilate/erode multithreading

another patch for the dilate/erode step method, still without any functional changes.
This time it keeps the general algorithm but uses the tile system to make it
multithreaded. I could not measure a speedup on my 2-core laptop, but hope that
it will be faster for more cores. The immediate speedup that is very visible though is
that tiles come in as soon as they are calculated and a dilate/erode node does not
block the whole image to be calculated.

till then, David.
