* feat(bevy_gltf_blueprints):
* added support for nested blueprints
* added example/test for nested blueprints with multiple levels of nesting
* feat(tools/gltf_auto_export):
* implemented functionality to export nested blueprints/collection instances
* added add prefs to control nested blueprints export
* experiments with nested blueprints merge modes
* when exporting of nested blueprints is disabled, will not scan for nested blueprints
and thus no export them
* docs(): updated docs & added images for nested blueprints support
* feat(tools): scene component injection & export
- ambient light, shadowmap resolution, bloom intensity, ambient occlusion are now directly settable from scene components that are injected automatically in the scene
- relaxed requirements for changes(aka when to export gltf) for main scenes,
so that render , background etc changes also trigger a save
- added scene components examples
- added additional proxies & handling for camera & lights
- in relevant cases, made sure that entity specific components are not overridden by scene components
- added option to toggle scene level exports of params/ components
- ambient colour/ intensity is now also set as background/clear colour
- updated docs
* updates both gltf_auto_export & bevy_gltf_blueprints to avoid duplicating common materials across blueprints
* feat(tools/gltf_auto_export): added materials library export !
* export all materials in use by blueprints to a separate temporary scene with cubes (for now)
with the materials assigned
* injecting MaterialInfo components to each blueprint above with Material name + library name
* generated gltf is named based on the project/blend file, so multiple blend file projects
can each have their own material libraries
* added preferences & ui & handling to be able to toggle material library exports
* feat(bevy_gltf_blueprints): added support for materials library!
* material injection (toggleable via the plugin configuration)
* added example
* added materials library + texture files + updated assets
* added physics debug toggling
* updated documentation
* closes#63
* restrict main_menu system to only run in AppState::MenuRunning
* this is desired because hitting enter once we transition to AppState::AppRunning pressing enter will still trigger keycode.just_pressed in main_menu and set state to AppState::AppLoading and crash the game when it tries to create another scene, camera, etc...
* settable via a config flag & systems won't run if the flag is not set
* caches aabbs per blueprint name so they do not need to be recomputed multiple time for the same blueprint
* closes#56
* added basic assets & logic for scene switching upon reaching a trigger zone ! Works !
* added toggling of physics debug
* added handling of nested colliders for LevelTransitions
* fix/ addition for point light intensity scaling & shadows
* closes#40
* feat(examples): added basic_xpbd_physics example
* adapted code from rapier physics
* updated blend file & exported gltf files
* changes & tweaks to cargo files so the examples are scanned as they should be
* various minor tweaks
* refactor(examples): moved examples into more logic folders & changed to allow for per example dependencies
* chore(): updated docs, added docs, updated deps , cargo files etc
