[svn-r10742] Purpose:
A little enhancement for integer datatype filter
Description:
Minimum-bit of the scaleoffset filter should not be less than 0,
However, if the user accidently input a negative value for integer type,
we will reset it to zero.
Solution:
Platforms tested:
too minor to test.
Misc. update:
