+    Various changes to allow tile buffers of more than 4giga pixels

+    Untested though, since that means a tile buffer of at least 16 GB. So

+
+    Remove limitation that prevents from opening images bigger than 4 billion pixels
+    
+    However the intermediate buffer for decoding must still be smaller than 4
+    billion pixels, so this is useful for decoding at a lower resolution level,
+    or subtile decoding.

+    Sub-tile decoding: only allocate tile component buffer of the needed dimension
+    
+    Instead of being the full tile size.
+    
+    * Use a sparse array mechanism to store code-blocks and intermediate stages of
+      IDWT.
+    * IDWT, DC level shift and MCT stages are done just on that smaller array.
+    * Improve copy of tile component array to final image, by saving an intermediate
+      buffer.
+    * For full-tile decoding at reduced resolution, only allocate the tile buffer to
+      the reduced size, instead of the full-resolution size.
