-----------------------------------------------------------

It's complex now...if a FilterListWithAND has two sub filters A & B, and  B has 
a row-level global state (such as column offset...),  after HBASE-18410, we 
optimze the forward step to be maximum, so we consider the return code from 
sub-filters at global level, which means that a cell may not be included the 
sub-filter A, but we still need to pass the cell to sub-filter B for 
calculating B' return code (for global return code purpose),  finally B's 
row-level global state messed up ...

> When ColumnPaginationFilter is combined with ColumnRangeFilter, we may see 
> incorrect result.
> Here is a simple example.
> One row with 10 columns c0, c1, c2, .., c9.  I have a ColumnRangeFilter for 
> range c2 to c9.  Then I have a ColumnPaginationFilter with limit 5 and offset 
> 0.  FileterList is FilterList(Operator.MUST_PASS_ALL, ColumnRangeFilter, 
> ColumnPaginationFilter).
> We expect 5 columns being returned.  But in HBase 1.4 and after, 4 columns 
> are returned.
> In 1.2.x, the correct 5 columns are returned.
