hdf5_ep

[svn-r3415] 
Purpose:
    bug fix
Description:
   two bugs: 1. different order of conventions of sds and image in hdf4 is
                 considered at h4toh5image.c file.
                  add palette colormodel attribute and correct names of
                   a few attributes. see detail at:
               http://hdf.ncsa.uiuc.edu/HDF5/H5Image/ImageDetails.htm
              2. convert hdf internal vdata structure(chunking table)
                 into a new hdf5 dataset.

Solution:
        1. change h5 data space order for image.
          h5dims[0] = edge[1]-edge[0];
          h5dims[1] = start[1]-start[0];
        2. at h4toh5main.c, check the vdata class name and if the
           first few characters match with HDF_CHK_TBL; ignore converting
           this vdata.
        3. add a few attributes at h4toh5pal.c

platforms:

       linux and sun 5.7(arabica)




    such as Big-endian-32bit (SUN/IRIX), little-endian-32(LINUX) and
    64-bit (IRIX64/UNICOS/DEC-ALPHA) would be good.]
