This is a parameter that will make the interpolation between irradiance
cells of a same Irradiance Volume smoother, reducing the weight of the
light leaking correction factors.
It is usefull in some cases to avoid harsh lighting transition that can
happen when a sample point it near a surface.
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 brings the functionality currently in the H shortcut, to hide/show
individual collections.
In order to convey hierarchy, and to make justice to the originally
intended 1-10 shortcuts, we group the collections per siblings.
While there is no support for dropping tools exactly,
the cursor tool supports a keyboard oriented workflow
which is often over-ridden by other tools key-maps
While many tools had shortcuts there was no fast way to get back to
the cursor tool.
Now double-tapping space sets the cursor tool
(as long as this tool doesn't have a key mapped).
This should be purely an implementation change,
for end users there should be no functional difference.
The entire key configuration is in one file with ~5000 lines of code.
Mostly avoiding code duplication and preserve comments and utility
functions from the C code.
It's a bit long but for searching and editing it's also convenient to
have it all in one file.
Notes:
- Actual keymap is shared by blender / blender_legacy
and stored in `keymap_data/blender_default.py`
This only generates JSON-like data to be passed into
`keyconfig_import_from_data`, allowing other presets to load and
manipulate the default keymap.
- Each preset defines 'keyconfig_data'
which can be shared between presets.
- Some of the utility functions for generating keymap items still
need to be ported over to Python.
- Some keymap items can be made into loops (marked as TODO).
