To fix this, we just scramble the halton sequence by multiplying by a large
prime number.
It seems to work fine in practice.
We also tried Sobol sequence but it has a less uniform pattern for low
number of sample.
Fix T68594 Eevee: Soft shadows causing flickering in animation and temporal AA in scenes
Before, it was only possible to fade the active object. The new option allows to fade all non gpencil selected object. This is a common request by artists.

I believed the crash I experienced happened because:
1. The `extract_pos_nor_init` function is called.
2. Tasks are added to the task pool for `extract_pos_nor`.
3. The tasks begin to be executed while more tasks are added.
4. In some rare cases, all existing tasks are finished, but not all have been added yet.
5. This let the task-counter go down to zero.
6. This triggered a call to `extract_pos_nor_finish`.
7. Then more tasks are added and in the end `extract_pos_nor_finish` is called again.
A solution is to use a task pool that is suspended when created.
Unfortunately, there was an outdated comment, that was probably the root cause of the issue.

This change implements the basics as described in {T68312} for the
shading modes.
* LookDev shading mode is renamed to Material Preview. It always uses Eevee as renderer, and is intended to provide a fast material preview suitable for texture painting, and texture and material setup.
* Rendered shading gains "Use Scene Lights" and "Use Scene World" options similar to current Material Preview. These will be enabled by default. When Use Scene World is turned off, HDRIs will be used for lighting instead. These options are available for EEVEE and Cycles.
* Renderers will be able to customize the shading settings panel and add additional settings.

Support for UV Stretching overlay during multi object editing. The
VBO now holds the ratios per fase. In the shader these ratios will
be compared against the global ratios. The global rations are created
from all selected objects.
The current implementation does not fit well with the draw module. The
plan is to move the drawing of other spaces towards the draw manager what
leads to a better fit. Currently the details on this solution is unclear
but this requirement will become an attentionpoint in the future design.

In weightpaint it is possible to enable the bone selection mode. During
drawing the overlay was rendered, but during selection this was ignored.
Users needed to double click in order to select bones even when the overlay
was enabled.
This patch makes bone selection possible during weight painting using the pose mode bone
selection overlay with a single click.

With Blender 2.80 we introduced a more flexible matcap system. One
change we did was to multiply the matcap with the base color that was
shaded. As matcaps contains diffuse and specular lighting in a single
texture this lead to rendering artifacts. Artists were complaining that
everything looked to metalic.
We now support a separate `diffuse` and `specular` pass for matcaps.
`shaded_color = diffuse_light * base_color + specular_light`
For matcaps to support this feature they need to be multilayer openexr
files with 2 renderpasses (named `diffuse` and `specular`). In the future
we can change this to first pass/second pass in stead of this naming
convention.

Before there were two options: Paste to original layer called "Paste" and Paste to active layer called "Paste & Merge"
Now, by default the paste is in active layer and the "Paste & Merge" has been renamed "Paste".
For old "Paste", now is called "Paste by Layer" and it's not the default value anymore.

The correct fix would be to avoid all those hacks but this is needed if
we want to be able to parallelize object vbo extractions.
This is the fixed version of the hack. The issue was that the ibo ranges
were saved before the batch were reset and the IBO was discarded, leading
to a read after free error. All previous reported crash were tested and
are now not reproductible.
Before, the evaluation of modifers were done in draw manager. The reason of the old design was grease pencil was designed before depsgraph was in place.
This commit moves this logic to depsgraph to follow general design and reduce Draw Manager complexity. Also, this is required in order to use modifiers in Edit modes.
Really, there is nothing really new in the creation of derived data, only the logic has been moved to depsgraph, but the main logic is the same. In order to get a reference to the original stroke and points, a pointer is added to Runtime data as part of the evaluated data. These pointers allow to know and use the original data.
As the modifiers now are evaluated in Depsgraph, the evaluated stroke is usable in Edit modes, so now it's possible to work with the evaluated version instead to use a "ghost" of the final image over the original geometry as work today.

The old layout of `PointerRNA` was confusing for historic reasons:
```
typedef struct PointerRNA {
struct {
void *data;
} id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
This patch updates it to:
```
typedef struct PointerRNA {
struct ID *owner_id;
struct StructRNA *type;
void *data;
} PointerRNA;
```
Throughout the code base `id.data` was replaced with `owner_id`.
Furthermore, many explicit pointer type casts were added which
were implicit before. Some type casts to `ID *` were removed.

This is a step to finish the D4325 and fix the T61286.
Currently the grid is highlighted in steps of 10 out of 10, which is wrong for the imperial units as seen in `buImperialLenDef`.
The idea of the code is to pass the steps of the grid already dimensioned as a uniform.
Another important thing to note is that subdivisions now only affect the grid without unity.
This matches the 2.7x Blender versions.
No performance loss (almost no gain too).

This was due to the GPUIndexBuf ranges only computed when requesting
the triangles indices. If the tris were already calculated, the new shading
batches would never have the GPUIndexBuf ranges and instead use the full
triangle index buffer.
So since this only happen when shading data does not match, we just save
the previous GPUIndexBuf ranges and reuse them for the new batch.
This patch is a bit of a hack on top of a hack but it works fine.
