This is no longer necessary, see: T98554.

Using object.update_tag() as pov specific object typing property set from python would not be visible from depsgraph before file save, causing mesh proxies to export rather than their pure untesselated pov shapes.

* 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 more consistent class names but cleanup still not finished
* 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

See T95597

* fix default open() encoding from strict system character set to utf-8
ignoring all other characters so Blender should no longer reject exotic
input pov files as mostly user declared names will probably get changed
in that process and likely everywhere the same way.

fix useless enumeration providing index in place of string

POV: Add primitives workspace tools icons, blurry reflections, equation based isourface ; various fixes

* 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)

In rB4ddad5a7ee5d9c3245593c509714f8c1359f9342
the `RENDER_PT_dimensions` class was renamed to
`RENDER._PT_format`

* 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

This reverts commit a8859502.

Fix : Removed some duplicate class that caused addon register /
unregister to fail after previous commit

Those were breaking automated tests, since (un)registering was not
working properly. Mainly:

* Use `hasattr` instead of try/except when batch-assigning to a variable
  that does not always exist.
* Fix some incorrect call to sub-`register()` from parent `unregister()`
  functions.
* Remove double definition (in two different files) of World's pov
  textures.

* 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

Reduces warnings while running tests.
Also fix some descriptions with strings concatenated but without a
space in between.

Add-ons shouldn't be printing information at startup.

*fix: too invasive default workspace, now only triggers if pov was saved to default renderer during previous session
*add: opening text editor sidebar to better show pov specific tools and text editing nature of the area.

Broken on rBAe44e5845ee2b

fix: Orthographic and perspective camera view angle thanks to Iari Marino
add: some numpy functions to export mesh possibly faster in next version
fix: parametric surfaces much accelerated and now actually usable (max gradient defaults were wrong from the time of their implementation in most pov literature. Thanks to William F. Pokorny for finding this out!
add: very basic "blurry reflection" hack for when using plain official POV
add: push of (as of yet badly formatted) feedback to interactive console
add: POV centric workspace, default when addon is left activated from previous session.
add: Sound signal support on finished render (set from addon preferences)
add: support for pov 3.8 and decremented in a few areas, waiting for the release
add: freestyle interface with convoluted workflow currently but preparing for next release.
fix: commented out Charset feature because POV 3.8 auto detects encoding
fix: a few dot notation look ups aliased and removed
fix: restored some more removed properties from 2.79 ( a few remain to do)
fix: texture mapped specular max value increased
fix: faster defaults for radiosity
fix: many default texture influences switched to 1 because boolean enabling is required anyway so 0 was a bad default
fix: some icons were missing since 2.8
fix: some formatting improvement was started

orthographic and cylindrical modes. best match for ortho.

* removed charset : The `charset` global setting has been deprecated in pov 3.8. Input files conforming to ASCII, UTF-8, Latin-1 or Windows-1252 encoding will instead be auto-detected, while other encodings are currently unsupported.

pre 2.8 property was still used. Now in the .pov. wrapper.

The module was renamed from smoke to fluid.

add back specular buttons removed since 2.8

used black on some files to dust up old formatting

Hoping it will help the code to be less repulsive to new developers.
