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).

This was caused by a wrong flag equality check when in xray mode because
the xray mode was masking the effect option flags that are not supported
in this mode. This means the never passed and the TAA was reset before

Regular rendering uses a custom blend mode, but render passes renders to

shader with the correct attachments.

The overlay options in the image/uv editor is hidden in side panels and menus. Sometimes this panel is even hidden, while still useful.
The goal of this task is to introduce an overlay pop-over just like the overlay-popover of the 3d viewport.
Popover has
* UV Stretching (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode)
* Display As (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode)
* Show Modified (only available in the UV mode, when active object mode is a mesh and in OB_EDIT mode)
* Show UV Edges (including opacity slider; available UV, View, Paint, when active object mode is a mesh and in OB_EDIT mode)
* Udim tiles when no image is available.
Like the 3d viewport, there will be a editor toggle to enable/disable the overlays
For compatibility reasons the RNA properties are added to both the `SpaceImage.uv_editor` amd `SpaceImage.overlay`. On DNA level they are still stored in the SpaceImage. only new properties are added to the SpaceImageOverlay struct. During the next major release we could remove these options from `SpaceImage.uv_editor`. This should be noted in the Python section of release notes.

The alloc was done in the init, but the free was done in the discard.
As discarding can happen more often there were some unneeded if
statements to work around use after free.
This patch moves the free to the `mesh_batch_cache_clear` and removes
the if statements to check for use after free.
This was introduced in 6c9ec1c893. The overlays can now be drawn when
PBVH drawing is not enabled, but the PBVH should still exist in the
SculptSession in order to draw them. Before, it was avoiding the crash
by checking use_pbvh as BKE_sculptsession_use_pbvh_draw also checks if
the PBVH exists.

The adds a new option to simplify volumes in the viewport.
The setting can be found in the Simplify panel in the render properties.
Volume objects use OpenVDB grids, which are sparse. For rendering,
we have to convert sparse grids to dense grids (for now). Those require
significantly more memory. Therefore, it's often a good idea to reduce
the resolution of volumes in the viewport.

Previously, one could only select a volume object in the outliner
or by clicking on the object origin. This patch allows you to click
on the actual volume.
Furthermore, the generated (invisible) mesh that is used for

With the new image editor drawing there were was some mutual exclusive
functionality. When rendering the alpha was shown correctly or the pure
emissive colors were shown correctly, but never both. The cause of this
is that the image_gpu did not used the correct alpha mode when generating
gpu textures for non-images (render results, compositors viewer)
The implementation always checked the alpha_mode. Alpha mode is an
attribute for images, but aren't set for non images. This patch adds
a more detailed check to ensure that the gpu texture is premultiplied.
The issue has been tested using several bug report files and production
files.
