* FIX: wrongly nested pov braces made the default outpout file fail
* FIX: use agnostic metallic property rather than create a duplicate
* FIX: some 2.8 deprecated properties rewired in spec;diff; emit;ambient
* FIX: clean up, hierarchize and redesign Global Settings ui panel
* FIX: re-wire world background alpha to agnostic prop and redo its ui
* FIX: wrong nested pov braces making the default outpout file fail
* FIX: use agnostic metallic property rather than create a duplicate
* FIX: reduced arguments numbers by imports and relocating variables
* FIX: use more list comprehesions to reduce nested conditions levels

* FIX: use single quotes for enums preferably to distinguish strings
* FIX: basic level of nodes based material (diffuse color) broken API
* FIX: blurry reflection corner case caused output file to fail
* FIX: added context managing ("with") syntaxes reducing crash cases

* RENAME: object_particles.py to particles.py
* fix tiny formatting of quotes, docstrings, parenthesis
* fix pov centered worspaces
* fix (revert) bad default for text block insertion
* fix primitive exports sorted by most frequent for (slight) speed up
* fix some uninitialized hairstrand root diameter variable
* fix extracted function for CSG inside vector
* fix too big size of proxy mesh for ininite plane caused it to blink
* fix end of render speach error handling
* fix max specular value to better map out under a texture influence
* fix emit, ambient, translucency shading properties UI broken post 2.8
* add workspace tools icons for pov primitives
* add a user input equation based isosurface primitive
* add micro normals based blurry reflections (glossy UI slider)
* fix: more imports cleanup and formatting
* add: hair shape (from old MaterialStrand for now)
* add: pixel / Non Blender units strand width
* fix: an exception handling of df3_library
* fix: gas flow_type typo
* Moved: some existing functions into new separate files to improve code
readability (detailed in __init__.py docstring)
* Remove: max_intersections deprecated in pov 3.8
* Add: Validate utf-8 characters with specific API function at session's
first script init
* Add : Icons to some text fields and inviting labels
* Change default camera normal perturbation value to non zero since its
use is first driven by a boolean toggle
* Change: lists (vectors and indices) are now exported in one line by
default for better manual scene overview and debugging
* Change: a couple of tooltips corrections
* Change : renamed many variables and functions to snake_case according
to recommanded style guides
* Fix : Heightfield primitive (forward slashes were expected for
displacement texture path)
* Fix : Text nippet insertion operator
* Fix : added console print tip to check executable path on failure to
process
* Fix : tweaked finished render say command for Linux
* Fix : interface of some shader nodes broken since 2.8 api changes
* Fix : export hair particles
