This patch adds an opacity slider to the wireframe overlay. The previous
wireframe in dense geometry scenes could be too dark and sometimes the

Perform grease pencil rendering delayed in this case, as there are no render
buffers available for compositing. This keeps memory usage lower, but does
involve multiple depsgraph evaluation. This seems in line with the intent of
the save buffers feature, to use minimal memory.
This is caused by the TAA being reset after the init phase, leading to
1 sample being kept as valid when it is clearly not.
To fix this, we run the lookdev validation before TAA init.

This patch will apply the view transform when a movie clip is used as
camera background image. It does this by rendering the image in the
color buffer when it needs the view transform. For other images it uses
the overlay buffer.

Issue was that the `tris_per_mat` are not created when the first batch is drawn
during select operator and then is not created when needed by the workbench pass
since they are not tracked by mesh_buffer_cache_create_requested.
This change will create the `tris_per_mat` just in case they are needed later.

This patch allows the user to type a property name into the
Attribute node, which will then output the value of the property
for each individual object, allowing to e.g. customize shaders
by object without duplicating the shader.
In order to make supporting this easier for Eevee, it is necessary
to explicitly choose whether the attribute is varying or uniform
via a dropdown option of the Attribute node. The dropdown also
allows choosing whether instancing should be taken into account.
The Cycles design treats all attributes as one common namespace,
so the Blender interface converts the enum to a name prefix that
can't be entered using keyboard.
In Eevee, the attributes are provided to the shader via a UBO indexed
with resource_id, similar to the existing Object Info data. Unlike it,
however, it is necessary to maintain a separate buffer for every
requested combination of attributes.
This is done using a hash table with the attribute set as the key,
as it is expected that technically different but similar materials
may use the same set of attributes. In addition, in order to minimize
wasted memory, a sparse UBO pool is implemented, so that chunks that
don't contain any data don't have to be allocated.
The back-end Cycles code is already refactored and committed by Brecht.

This was caused by unprotected drawing callbacks.
As of 2.91, we require that all python callbacks used for
drawing needs to be safeguarded by `GPU_bgl_end()` to end the
state tracking override.
This patch helps the case of intricate reflections where the
ray does not travel far before intersecting the geometry.
In these cases there could be false negative exclusion of the ray
caused by the backface rejection threshold.
The artifact manifested as lines of different values caused by faillure to
trace the depth buffer correctly.
Adding a ad-hoc value to the step size to mitigate the issue.
Currently render passes in the draw manager (eevee) must be predefined
in the render result. This patch would ask the render engine for the
render passes it needs, and create these as a preparation step during
rendering. This allows any draw engine to define more complex render
passes setup.
Render passes can only be added before the call to `RE_engine_begin_result`.
`RE_engine_begin_result` makes a full copy of the render passes. During
rendering the render engines renders to the duplicated passes.
`RE_engine_end_result` syncs the data back to the original render passes,
but only if the passes existed in the original render result.
Currently we work-around this issue by registering the passes in
`render_result_new`. This is legacy blender internal structure and should
be avoided.
With upcoming projects (AOV/Cryptomatte) it becomes a bit of a mess as we
are extending legacy code to support new features. This patch allows us to
let each draw engine register their own render passes at render time
(similar to cycles and other render engines). In the future we could get
rid of legacy render passes registration in render_result_new.

This patch fix most self intersection comming from reflection rays.
We regenerate the ray if it goes below the shading normal (should be the
geometric normal but we have no access to it here).
Also add the same precision based bias we use for contact shadows.

This changes how the simplify volumes setting works. Before, it only
affeted viewport rendering. This was an issue, because all internal
computations would still have to happen on the high resolution volumes.
With this patch, the simplify setting already affects file loading and
procedural generation of volumes.
Rendering does not have to care about the simplify option anymore,
it just gets the correct simplified version from the depsgraph.

Issue caused by {9582797d4b50} in b2.90. The surface per material used
an index buffer owned by the batch. These index buffers are created at
the same time the surface tris index buffer was created. When a material
per batch buffer was invalidated it used the surface tris index buffer
rendering all materials on all surfaces making the last draw command
render succeed.
This patch stores the surface tris per material in the cache so they can
be reused. There is also no need to use the `saved_elem_ranges` anymore as they are
now part of the cache.
The ugly bit of the implementation is that in `extract_tris_finish` the
MeshBufferCache is retrieved. But as this part was already documented as
a hack and it is something that is only used for final meshes. Other
solutions would impact performance or made the fix not condensed
(passing parameters that shouldn't be used).
