   Return a new tile containing the inclusive prefix maxima of a tile.
   
   This is a cooperative operation: the threads of the block divide the work between
   them, so every thread must reach the call.
   
   Element ``i`` of the result is the maximum of input elements ``0`` through ``i``.
   Comparisons follow C ``fmax`` semantics.
   A multi-dimensional tile is scanned over its flattened row-major sequence and the
   result keeps the input shape. On CUDA, this operation reserves a tile's worth of shared
   memory (see :ref:`tile_shared_memory_budget`).
   
   :param a: The input tile, with dtype :class:`warp.float32`, :class:`warp.int32`, or
             :class:`warp.uint32`.
   
   :returns: A register tile with the same shape and dtype as ``a``.
   
   See :func:`~warp.tile_scan_inclusive` for a usage example.
