Returns the actual, used size of the section. 
This field may be larger or 
smaller than the SizeOfRawData field. 
If the VirtualSize is larger, the 
SizeOfRawData field is the size of the 
initialized data from the executable, 
and the remaining bytes up to the VirtualSize 
should be zero-padded. This field is set 
to 0 in OBJ files.
