1.131 - 2025-07-01

Highlights include:

- Added `HeightReference` to `Cesium3DTileset.ConstructorOptions` to allow clamping point features in 3D Tile vector data to terrain or 3D Tiles [#11710](https://github.com/CesiumGS/cesium/pull/11710)
- Added the ability to pass `OffscreenCanvas` & `ImageBitmap` directly to `Material` uniforms. [#12558](https://github.com/CesiumGS/cesium/pull/12558)
- Fixed raymarching step size for cylindrical voxels. [#12681](https://github.com/CesiumGS/cesium/pull/12681)
- Fixes handling of tileset `modelMatrix` changes for translations and rotations in `GaussianSplatPrimitive`. [#12706](https://github.com/CesiumGS/cesium/pull/12706)
    - Experimental support for loading 3D Tiles with Gaussian splats encoded with SPZ compression was added in the previous 1.130.1 release [#12582](https://github.com/CesiumGS/cesium/pull/12582)
