[svn-r8007] Purpose:
Bug fix
Description:
Range check the szip 'pixels per block' against the chunk size of the
dataset when attempting to create a new dataset, since the szip library
requires the PPB to be at least the size of the fastest changing dimension
in the chunk.
Platforms tested:
FreeBSD 4.9 (sleipnir)
too minor for h5committest
