Avoid RenderGroupKey allocations

This would allocate a lot easily 60Mb/s.
Instead of a dedicated struct we now compute a 64bit hash and use that for render grouping.

Remove per frame HashSet, List and LINQ allocations

* More accurate and less allocation heavy version of Task.Delay

- Shoot a single task delay for longer intervals
- Only use expensive polling for the last sub threshold

* Avoid ExecutingJob allocations when not tracking jobs

* Start moving SSR to bindless

* Classify pass stub

* Separable bilateral upscale, 0.3ms > 0.08ms, not happy with it still

* start classify and intersect indirect

* Commandlist support for UAV barriers and clearing a texture and gpubuffer

* Simplify this, move classify to it's own shader

* All indirect

* ResourceState.IndirectArgument missing from ResourceStateToVulkanFlags switch

* Fix indirect, all works

* classify doesnt get skybox

* Add Clear method to CommandList for clearing render target colors

* bilateral upscale indirect too

* Cleanup

* Simplify bilateral upscale, With RADIUS=1, separable saves only 3 taps (6 vs 9), but costs 3 barriers + shared memory + atomics — the synchronization overhead far exceeds 3 extra texture loads of doing it with a normal X Y loop

* Dotnet format, increase roughness threshold (we can afford it 😘 ) and dont need to discard these buffers on disable

* compile shaders

* this shouldnt be a property

* Add FillGPUBuffer method for efficient buffer filling using native GPU commands

CollisionEventSystem is quite alloc heavy especially the action wiring causes 10+ heap allocations per collider.

Collect pending acks in List rather than spamming async tasks.
Process List in Tick.

So we don't allocate when a GameObejct doesn't have any tags
Fast & alloc free pass for GameTags.SetFrom

Let's see if this helps

* Remove unnecessary static singletons in MainMenu code

* Empty SceneWorld delete queues during shutdown

* Dresser cancel async load operation on destroy

* Use reflection to null references to static native resources on shutdown

This way we don't  have to remember doing this manually.

* Fix SoundOcclusionSystem using static lists to reference resources

* Sound System: Use weak references to refer to scenes

* Cleanup static logging listeners that kept strong refs to panels

* UISystem Cleanup, make sure all panel/stylesheet refs are released

* RenderTarget and RenderAttributes shutdown cleanup

* Rework AvatarLoader, ThumbLoader & HTTPImageLoader Cache

First try to go through ResourceLibrary.WeakIndex which might already hold the texture.

If there is no hit, go through a second cache that caches HTTP & Steam API response bytes instead of textures.
We want to cache the response bytes rather than the actual Texture, so stuff cached sits in RAM not VRAM.
Before avatars and thumbs would reside in VRAM.

* Fix rendertarget leak in CommandList.Attr.SetValue

GetDepthTarget() / GetColorTarget() return a new strong handle (ref count +1).
We need to DestroyStrongHandle()  that ref. So handles don't leak.

* Call EngineLoop.DrainFrameEndDisposables before shutdown

* NativeResourceCache now report leaks on shutdown

* Override Resource.Destroy for native resources, kill stronghandles

* Deregister SceneWorld from SceneWorld.All during destruction

* Ensure async texture loading cancels on shutdown

* SkinnedModelRender bonemergetarget deregister from target OnDisabled

* Clear shaderMaterials cache during shutdown

* Refactor Shutdown code

Mostly renaming methods from Clear() -> Shutdown()
Adding separate GlobalContext.Shutdown function (more aggressive than GlobalContext.Reset).
Clear some static input state.

* Deregister surfaces from Surface.All in OnDestroy

* RunAllStaticConstructors when loading a mount

* Advanced managed resource leak tracker enabled via `resource_leak_tracking 1`

Works by never pruning the WeakTable in NativeResourceCache.
So we can check for all resources if they are still being held on to and log a callstack.

* Support types like Curve, Gradient, ParticleGradient in movies
* Fix TransformOperation.OnReduce: old implementation was nonsense, could stack overflow
* Add optional filePath parameter to GenerateScreenshotFilename
* Force movie project to save even if we don't think it's changed
* ITemporaryEffect.IsActive pseudo-property for movie recordings
* Add ITrack.GetPathString() extension
* Safety when trying to compress a sample block
* Skip updating playback rate on renderers with a bone merge target
* Move PropertySignal<T>.FromSamples to PropertySignal
* Fix view not always updating when zooming
* Enabled tracks defaults to false when applying
* Movie export: manually call Scene.EditorTick, pause updates elsewhere (fixes #10137)
* CanMakeTrackFromProperties: default to only allowing user types

Introduced in Facepunch/sbox#4242 , which added some additional panel cleanup

Ignore static members when serializing or cloning components, makes no sense and breaks cloning with Expression Trees (that was introduced in Facepunch/sbox#4202)

Fixes #10161

Synthesizer never disposed its SpeechSynthesizer, causing background VoiceSynthesis threads to accumulate indefinitely (30+ seen in crash dumps).
This may have caused crashes in TTS heavy games like DXRP.

In addition we now properly terminate the SoundStream so SoundHandle.IsPlaying will become false after the stream has been played.

See: #4184

Needs to be rethought, it gets in the way often -- keeping view handle though

This should have changed with 36439d4

* Sync localisation files to clients thru network files
* Changing lang triggers Panel.LanguageChanged again, so we can rebuild panels, labels, etc.

* Init ActiveFriends as Enumerable.Empty

* Snip IconPanel logging its url

Fix transform update regression from 7b853ce

Rotation.AlmostEqual default threshold was too loose (0.0001 dot-product ~ 1.62° angular tolerance), causing SetLocalTransform to silently drop small transform updates.

- Rotation.AlmostEqual: default delta 0.0001 -> 0.0000001 (~0.05°), use MathF.Abs(Dot) to handle antipodal quaternions (q === -q)
- Transform.AlmostEqual: use Rotation's own default instead of passing the Position/Scale delta to a dot-product metric

This reverts commit 2caf916.

Add `DeferGeneration` property to skip navmesh generation during scene load, allowing tiles to be generated and unloaded on demand at runtime.

New public API:
- `NavMesh.DeferGeneration` - skip tile generation on load
- `NavMesh.RequestTileGeneration`/`RequestTilesGeneration` - fire-and-forget via cache loop
- `NavMesh.UnloadTile`/`UnloadTiles` - remove tiles from the navmesh

* preload resolutions on init

- rewrote CameraOrbit logic
- moved panning from FirstPersonCamera to CameraOrbit
- changed logic within SceneViewportWidget / PageSceneView / EditorPreferences to adjust for new SceneEditorExtension changes

Managed will queue deletion no need to check for proper destruction this early

- final code clean-up
- fixed a issue where when the raycast within zoom didn't hit anything, it used the world origin as the reference point instead of the last hit performed by either orbit/zoom or pan
