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.

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.
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 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
every redraw, leading to infinite rendering.

The volumes are not a line type and should not be render into the line
framebuffer nor it should change the framebuffer.
Regular rendering uses a custom blend mode, but render passes renders to
2 separate textures. This wasn't configured correctly inside the
fragment shaders. This patch adds a switch to configure the fragment
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.

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.

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
selection is also used to draw an outline for the volume object now.

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.

This is a simple trick that does *not* have a huge performance impact but
does work pretty well. It just modifies the Fresnel term to account for
the multibounce energy loss (coloration).
However this makes the shader variations count double. To avoid this we
use a uniform and pass the multiscatter use flag inside the sign of f90.
This is a bit hacky but avoids many code duplication.
This uses the simplification proposed by McAuley in
A Journey Through Implementing Multiscattering BRDFs and Area Lights
This does not handle area light differently than the IBL case but that's
already an issue in current implementation.
This is related to T68460.

This implements a new overlay that blends the bakground color over the
objects that are not in the same mode as the active object, making
them fade with the background.
This is especially needed for sculpt mode as there is no other overlay
or indication in the viewport to display which object is active.
This is intended to be used with D7510 in order to have a faster
workflow when sculpting models with multiple objects.

This adds an option for the HDRI rotation to follow the view rotation.
When this option is enabled, this allows EEVEE materials to be used as
matcaps for sculpting and painting.
This has an extra performance cost when orbiting around the model as the
lookdev cache needs to be recalculated, but in my test it is barely
noticeable.

This new feature allows to use the strokes as an eraser of any stroke below. This is very handy to open holes in filled areas.
After running some tests, we have decided to keep the additive effect of the holdout color. To get clean holdout areas, just move the color to black to remove any additive effect. To have additive effect can be used in situations like tint slightly a transparent window with blue to simulate the glass.
