[svn-r10067] Purpose:
feature
Description:
h5repack support for scaleoffset compression
Checking in early to help debug the filter.
Solution:
Added messages and command line to handle new scale offset filter.
Note: TESTS ARE DISABLED FOR NOW. The filter is not
complete, repack tests may fail due to know problems.
PLEASE DO NOT MESS WITH THE SCALEOFFSET TESTS AT THIS TIME.
