Interface PrimitiveMeshIndexTexturePortionHandle

Handle to an allocated portion in PrimitiveMeshIndexTexture.

A portion represents a contiguous range of primitives belonging to a single mesh and assigned to a specific render pass.

Portions are opaque handles owned by the texture. Their offset is updated during uploadChanges, when the internal buffer is rebuilt and repacked.
