- Returns an empty list when there's not registered plugins, thus preventing the creation of spurious iterator objects
- Inline `Godot#getRotatedValues(...)` given it only had a single caller. This allows to remove the allocation of a float array on each call and replace it with float variables
- Disable sensor events by default. Sensor events can fired at 10-100s Hz taking cpu and memory resources. Now the use of sensor data is behind a project setting allowing projects that have use of it to enable it, while other projects don't pay the cost for a feature they don't use
- Create a pool of specialized input `Runnable` objects to prevent spurious, unbounded `Runnable` allocations
- Disable showing the boot logo for Android XR projects
- Delete locale references of jni strings
On Android the exit logic goes through `Godot#onDestroy()` who attempts to cleanup the engine using the following code:
```
runOnRenderThread {
GodotLib.ondestroy()
forceQuit()
}
```
The issue however is that by the time we ran this code, the render thread has already been paused (but not yet destroyed), and thus `GodotLib.ondestroy()` and `forceQuit()` which are scheduled on the render thread are not executed.
To address this, we instead explicitly request the render thread to exit and block until it does. As part of it exit logic, the render thread has been updated to properly destroy and clean the native instance of the Godot engine, resolving the issue.
This is disabling the logic added in #84974 which caused #94416.
That issue still needs to be debugged further, but this works around
the regression and should have minimal usability impact on Android.
When UVs are mirrored in a mesh, collapsing vertices across the
mirroring seam can significantly reduce quality in a way that is not
apparent to the simplifier. Even if simplifier was given access to UV
data, the coordinates would need to be weighted very highly to prevent
these collapses, which would penalize overall quality of reasonable
models.
Normally, well behaved models with mirrored UVs have tangent data that
is correctly mirrored, which results in duplicate vertices along the
seam. The simplifier automatically recognizes that seam and preserves
its structure; typically models have few edge loops where UV winding is
flipped so this does not affect simplification quality much.
However, pre-processing for LOD data welded vertices when UVs and
normals were close, which welds these seams and breaks simplification,
creating triangles with distorted UVs.
We now take tangent frame sign into account when the input model has
tangent data, and only weld vertices when the sign is the same.
