The name of the stream (used as texture uniform name).
OptionalstorageStorage type: GSPLAT_STREAM_RESOURCE (default, shared across
instances) or GSPLAT_STREAM_INSTANCE (per-component instance). Note: Work buffer formats
(accessed via app.scene.gsplat.format) do not support GSPLAT_STREAM_INSTANCE.
The pixel format of the texture (e.g. PIXELFORMAT_RGBA32F). When used as an extra stream for work buffers or as a destination stream for GSplatProcessor, the format must be renderable as these textures are used as render targets. Ensure the format is renderable on all target devices. See Texture for details on renderable formats and device capabilities.
