[svn-r8969] Purpose:
Bug fix. Description: Address two problems: - The computation of the scanline in the szip filter was being performed in the "can apply" callback routine instead of the "set local" routine. - The routine which allocated all the chunks for an entire dataset (which is invoked when the allocation time is early or late, rather than incremental) wasn't recording a failed filter in the information for the chunk, causing the library to believe that the chunk had the filter applied when it really hadn't. Solution: - Move the scanline computation to the "set local" callback. - Record the filter mask with each chunk created when allocating them. Platforms tested: FreeBSD 4.10 (sleipnir) w/szip Too obscure to require h5committest

Library
-------
+ - Fixed obscure bug where a filter which failed during chunk allocation
+ could allow library to write uncompressed data to disk but think
+ the data was compressed. QAK - 2004/07/29
- Fixed bug where I/O to an extendible chunked dataset with zero-sized
dimensions would cause library to fail an assertion.
