* added a fix for BlueprintInfo path issues on non posix platform by replacing specific
os.path.join calls with posixpath.join ones (blueprint info paths, export_path, material_path etc)
should hopefully solve spawning issues on Windows
* restructured & improved materials export: now uses same logic as blueprints, with seperate determining of
what materials changed & the export itself
* minor tweaks
* coherence pass : "main" scenes & co renamed to "level" scenes & co
* auto export now toggled ON by default, but bailing out early if there are no main & lib scenes added
* UI improvement for adding level/lib scenes
* minor cleanups
* injected BlueprintAssets are now reusing existing asset scan boilerplate (wip)
* added back per blueprint assets
* experimenting with how to export all vs local only assets
* renamed (finally) export main scenes
* found issue with scene serialization (hellooo collections !), working on fix
* fixed issue with parenting due to Blender's very weird matrix_parent_inverse ... solves all issues with children of empties
blueprint instances within blueprint instances etc having the wrong transforms in some cases
* fixed bad gltf format propagation: semi ok solution, but a cleaner one would be better
* added additional custom properties to the blacklist , level/blueprint exports are now using the one in the constants
instead of a local copy
* minor tweaks & cleanups
* fixed bad hashing causing hashed project across two different blender sessions to appear different
aka, no more systematic re-export of everything when reloading a project in blender !
* fixed issues with modifier & material hashing that was also causing overly eager change detection
* previous_xxx_settings are now only saved AFTER a sucessfull export, for coherence
* added more fine grained setting change detection (aka some setting changes do not require a re-export of all levels & blueprints !)
* fixed handling of level & library scene names as part of the settings
* fixed numerous issues with core, auto_export & component settings
* cleaned up a ton of very verbose debug message
* BlenvyAssets => BlueprintAssets
* a lot of minor cleanups
* fixed handling of scene gltf_extras
* fixed handling of colors for BlenderBackgroundShader
* added scene tonemapping & scene colorgrading and handling on the Bevy side.
* experimented with exporting ron asset files, updated & overhauled asset file generation, adapted
for blueprints
* various cleanups
* fixes & experiment to auto export
* added support for "always export" functionality for blueprints & levels
* fixed issues with asset management
* fixed issues with tracker
* more ui improvements (display of the number of assets etc)
* a lot more minor tweaks
* fixed/ overhauld asset & blueprint scanning
* added polling for blueprints (not 100% sure yet)
* add-on-prefs => settings
* removed the now obsolete auto-export operator & preperences
* a lot of other minor changes
* removed a lot of obsolete code
* overhauled settings upsert
* added save & load of blenvy common settings
* removed most of the specific uis (mostly auto export)
* moved change detection logic out of auto export (wip)
* added helper to compare setting dicts
* cleaned up some incoherent naming
* stripped auto_export of a lot of its internals (wip)
* main settings ui overhaul: now components & auto export provide their own settings UI function
* added Asset propertygroup & User Assets collections to collections & scenes to store them explicitely
* overhauled UI to make use of this : also means names & paths are editable after the fact
* overhauled testing asset hierarchy scan accordingly
* added expertimental export of bevy_asset_loader compatible asset.ron files per level
* related tweaks & additions
