2017-09-01	Various changes to allow tile buffers of more than 4giga pixels	Even Rouault
	Untested though, since that means a tile buffer of at least 16 GB. So there might be places where uint32 overflow on multiplication still occur...
2017-09-01	Sub-tile decoding: only allocate tile component buffer of the needed dimension	Even Rouault
	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.
