  Returns a copy of the data of the specified buffer, optionally offsetBytes and sizeBytes can be set to copy only a portion of the buffer.

• func bufferUpdate(buffer: RID, offset: UInt32, sizeBytes: UInt32, data: PackedByteArray, postBarrier: RenderingDevice.BarrierMask) -> GodotError

  Updates a region of sizeBytes bytes, starting at offset, in the buffer, with the specified data. Raises a memory barrier except when postBarrier is set to .noBarrier.
