Log:
* gegl/buffer/gegl-buffer-private.h: added ->storage field to cache
the GeglStorage of a buffer.
* gegl/buffer/gegl-buffer.c:
(get_tile): replace type-checked casts, replace lookup of storage
with the cached version in the buffer itself.
(gegl_buffer_iterate): lookup the tile_width and tile_height on cached
GeglStorage instead of traversing buffer chain to get at storage.
* gegl/buffer/gegl-buffer-allocator.c: (gegl_buffer_alloc): make
direct use of the buffer->storage.
* gegl/buffer/gegl-buffer-save.c: (gegl_buffer_save): make direct use
of buffer->storage.
