This patch is only for optimizing excel8 type. 
In filter process, just update row heights for : 1. visible sheet, 2. sheet
containing sdrobject.

following is test result for sample file sc_complex_13sh_4kcell.xls(manual
test), about 20% improvement. 
old: 3.90 3.93 3.78 3.75 3.75 3.85 3.84 3.87 4.00 4.00    avg:3.87
new: 3.03 3.03 3.06 3.03 3.06 3.09 3.06 3.12 3.09 3.15      avg:3.07
