Some features are incompatible with multithreading and reliable evaluation
of dependencies. We are now removing them as part of a bigger cleanup to
fix bugs in keyframing and invalid animation evaluations.
* Dupliframes have been removed. This was a hack added before there were
more powerful features like the array modifier.
* Slow parent has been removed, never worked in 2.8. It was always
unreliable for use in production due to depending on whatever frame was
previously evaluated, which was not always the previous frame.
* Particle instanced objects used to have their transform evaluated at
the particle time. Now it always gets the current time transform.
* Boids can no longer do predictive avoidance of force field objects,
but still for other particles.

This adds the posibility of having certain materials transparent in solid
mode. The option is (for now) per material only and thus only shows in
material color mode.
This uses the same rendering technique as Xray mode.
Note that objects are not considered transparent for selection with this.
The subdivision method for getting corner shapes has a fullness
parameter which had been set by eye before. This change uses fullness
as found by offline search process to best match the superellipsoid
octant in the cube corner case (except cube corner case is still handled
by other code). This somewhat improves the look of cube corners with
inner arc miters, however.
Render-type panels are only shown when the relevant type is active anyway.
Saves a click especially when using object or collection as render, since
you _have_ to set an object or collection to use it.
this can now be found in the sidebar View panel
- uses existing 'lock_camera_and_layers' but renames the property to
'use_local_camera'
- uses RNA_def_property_boolean_negative_sdna to flip the value
- remove the local view code in
rna_SpaceView3D_lock_camera_and_layers_set
- update Python code
- update Addons code will be separate commit

There were two problems:
1. The scopes were only updated when the "Scopes" category is active,
but this category has been removed in Blender 2.8.
2. The scopes moved from the TOOLS to the UI region.
However the update-code still searched for the "Scopes" category
in the TOOLS region.
Both problems are fixed with this commit:
1. Scopes have there own category again.
2. The update code is in the correct draw function now.

This helps to generate cleaner topology and define sharp features for dynamic
topology. Best used on relatively low-poly meshes, it is not needed as much
for high detail areas and has a performance impact.

It is possible that context does have selected_sequences but
it will be set to None. In this case getattr() will return
None, breaking the intended logic.
Allows users to select a font for text strips in the video sequence editor.

Cycles shows first the render, and then the viewport settings.
One could argue that EEVEE's main setting is the viewport one.
But that is silly. If we need an extra setting for the lookdev mode so be it.
But EEVEE should be treated as an engine just as Cycles.
Also, removed the " Samples" bit from their labels since they are under
the Sampling panel.
Will document the new options in release notes, then in manual.
Still a bit of work to do on the bulging shape that appears
on cube corners if using arc inner miters, but will do that later.
Also need to do something smarter in clamp overlap.
Some of Eevee's Bloom defaults are not very good for physically based rendering. This patches addresses this issue.
This picture shows one of the problems with current default. Bloom looks very foggy:
{F6280495}
Even worse, light emitters much dimmer than the Sun can make everything equally hazy if Clamp is set to 1.0 and intensity to 0.8 (current default). Artists often forget to adjust Clamp value and do not know what value to use for realistic intensity. Also, currently both Clamp and Intensity do not have good UI ranges. This is why often Eevee renders end up very hazy and bloom often does not look right.
Bloom effect plays important role to help to distinguish between bright and relatively dim light sources. With current defaults this is broken because Clamp set to 1.0. Also, it cannot be disabled if set to 0 like expected. This patch fixes this and sets it to 0 by default. If users need to clamp, they can do so easily with UI range up to 1000. This range is good enough for most cases and provides enough precision to control lower values, and the highest value helps to limit bloom from the Sun if necessary and will leave untouched most other light emitters. If needed, much higher values for Clamp can be entered manually up to 100000. 10000 is still affects the Sun, but up to 100000 highest limit allows to clamp anything that is much brighter than the Sun if user needs to limit bloom in such cases (for example, bright explosion in the sky or anything else very bright).
I propose new default for bloom Intensity - 0.05 and UI range to suggests realistic values. Bloom Intensity > 0.1 is not realistic for clean lens but the user can enter manually much larger values if needed.
For comparison, here is a my own photo with and without bloom caused by the Sun (on second photo the Sun was occluded with an object).
{F6280500}
{F6280492}
In real life bloom is much more subtle and does not look hazy. If Clamp is disabled, then out of 0.1, 0.05 and 0.025 values I have tried, 0.05 looks most similar to the photo. Here is test render with and without bloom with the Sun in similar position like on the photo:
{F6280496}
{F6280494}
Using color probe 27x27 I compared lightness below the horizon under the Sun. In rendered by Eevee images lightness difference was 17. In case of the photos lightness difference in similar place was 11. I then compared leftmost spot (also below the horizon) and lightness difference was approximately 2 between two photos and 1 between rendered images. In other words, with these settings bloom effect is not too strong and is not too weak. Visually it may seem like decreasing bloom intensity may increase photorealism, but then bloom effect would be too localized even for the Sun.
Besides this single test, I tested in many other scenes as well, with and without the Sun, with different HDRIs, and as far as I can tell 0.05 intensity turned out to be good default - it produces bloom strong enough to be noticeable and not too hazy.
In Cycles shutter default value is 0.50, so for consistency set to 0.5 by default in Eevee too. Besides, 0.5 is typical standard for real cameras, and values higher than 0.5 usually are needed only if very strong motion blur is desired.
Here is summary of all changes:
Bloom Intensity: 0.8 > 0.05
Bloom Intensity UI range: 0-10 > 0-0.1
Bloom Clamp: 1.0 > 0.0 (disabled by default)
Bloom Clamp manual range: 0-1000 > 0-100000
Bloom Clamp UI range: 0-10 > 0-1000
Shutter: 1.0 > 0.5
This patch is related to the discussion in this thread, there are more examples of what bloom will look like with 0.05 intensity by me and others:

This further changes the preferences organization, to avoid grouping unrelated
settings together. With more sections we can also expand more panels by default,
making it possible to quickly go through sections and see the settings of each.
Panels with less used settings are still collapsed by default, to keep all panel
headers visible without scrolling.
