The billboard particles were only used by Blender Internal. So until it is
supported by Cycles of Eevee there is no reason to keep it in the code and
UI.
Fix T61695 Billboard particles not displaying in Eevee viewport, render
Confusing to call a menu a panel when subclasses need to define
panel specific variables.
Avoid having bl_ui depend on bl_operator module too.
Since this isn't an operator, add utils modules for shared types.
In keeping with convention to match code & UI naming.
- No user visible changes.
- Include 'menu' in the name since context is an overloaded term.
- While a few of these are panels, from a user perspective they are
still context menus.
Some properties were accidentally hidden for particle fluids.
- Made sure we show the Forces and Integration
sub-panels for particle fluids.
- Slightly re-ordered the sub-panels here, so that the same sub-panels
are at the top for Newtonian and Fluid particles.
- Separated the Fluid Interaction sub-panel so we can give it a unique
name.
- Removed lingering unnecessary 'Keys' label in the Keyed physics.
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.
* Icons in specials menu (Copy and the new Duplicate icon)
* Remove redundant "Settings" label next to ID template widget.
* Remove "Type" label and expand dropdown, since it only has 2 options (emitter/hair), saves 1 click.
* Move "Seed" to and "Hair Segments" to Emission panel
* Rename "Duplicate Particle Systems" to "Duplicate Particle System", since it
only duplicates one (the active one) at a time.
Misleading name since it's between 0..1.
Use as a keyword argument to prepare for keyword only args.
Also document that leaving unset has special behavior.
This is intended for quick renders for previsualization, animation previews
or sequencer previews. It provides the same settings as found in the 3D view
Shading popover in solid display mode, but in the scene render properties.
The "Workbench" engine was removed, and this name no longer appears in the
user interface, it's purely an internal name. We might come up with a better
name for this OpenGL engine still, but it's good to be consistent with the
OpenGL Render operator name since this has a similar purpose.
There is now a manual refresh button on the panel to update the list
of objects in case it changes, and it also gets refreshed when changing
the collection or toggling the use count option.
This is a bit more manual but the previous code of refreshing the
list while evaluating the depsgraph was unreliable.
This also fixes it to take properly take into account visibility, and
to work with linked collections for which index writing was missing.
Force Fields and Falloff are now simpler and more compact
by removing unnecesary labels (there was a text label just for one option)
Particle Force Fields Falloff is now a sub-panel of each effector type,
rather than just as a section with label.
Moves the preset into a menu for the panel header, so it can be changed
without opening the panel and takes up less space. Two remaining issues:
* For long lists the add new preset button can be scrolled off screen.
* We should support showing the name of the chosen preset in the panel
header, but the current preset system does not support detecting which
preset is used.

The ClayEngine was introduced to test the blender2.8 architecture during
development. As currently we have the wanted features implemented with
matcaps we are going to remove the clay engine as it was never intended
to be an official releasable engine
Note: The test cases are never run. But when enabled will be skipped as
they were implemented over the Clay Engine
