Compared to the previous implementation this has a limit of 65536 lights
per scene. Lights exceeding this limit will be ignored.
This also introduce fine grained GPU light culling, making rendering
many lights in a scene more efficient as long they don't overlap much.
Compatible light panels have been unhidden.
Note: This commit does not include surface evaluation, only light culling.

It can be assumed that all scripts comply with basic pep8 formatting
regarding white-space, indentation etc.
Also remove note in best practices page & update `tests/python/pep8.py`.
If we want to exclude some scripts from make format,
this can be done by adding them to `ignore_files` in:
source/tools/utils_maintenance/autopep8_format_paths.py
Or using `# nopep8` for to ignore for individual lines.

Use a shorter/simpler license convention, stops the header taking so
much space.

While most of the source tree has been included
- `./extern/` was left out.

This adds 2 new sliders for light objects that modulates the diffuse
light and the volume light intensities.
This also changes the way volume light is computed using point lamp
representation. We use "Point Light Attenuation Without Singularity"
from Cem Yuksel instead of the usual inverse square law.

This appears to just have been a simple copy/paste mistake

This is the angular diameter as seen from earth, which is between 0.526° and
0.545° in reality. Sharing the size with other light types did not make much
sense and meant the unit was unclear.

Material was already there. Implementation was changed so it's just a
single line of code to adapt a panel to the node editor.

Neither is very descriptive for its task, but at least workbench is more
future proof and distinguishes it from Eevee.

This is an important change. Starting from now, all lights have a finite
influence radius (similar to the old sphere option for BI).
In order to avoid costly setup time, this distance is first computed
automatically based on a light threshold. The distance is computed
at the light origin and using the inverse square falloff. The setting
can be found inside the render settings panel > shadow tab.
This light threshold does not take the light shape into account an may not
suit every case. That's why we provide a per lamp override where you can
just set the cutt off distance (Light Properties Panel > Light >
Custom Distance).
The influence distance is also used as shadow far clip distance.
This influence distance does not concerns sun lights that still have a
far clip distance.
---
This change is important because it makes it possible to cull lights
an improve performance drastically in the future.

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.

Also close Preview panel for lights by default and move World custom props last

|
Internally it's still mostly named lamps, though some modules like Cycles
were already calling them lights.
