hdf5_ep

[svn-r8915] 
Purpose: Improvement

Description: HDF5 Library set pixels_per_scanline parameter to the size of the chunk's
             fastest changing dimension.  As a result, fastest changing dimension
             of the chunk could not be bigger than 4K and smaller than pixels_per_block
             value and szip compression couldn't be used for many real datasets.

Solution: Reworked algorithm how HDF5 sets pixels_per_scanline value; only chunks
          with the total number of elements less than pixels_per_block value are rejected.
          There is no restriction on the size of the chunk's fastest changing
          dimension anymore.
