* \brief Options for so called "simple" filters
*
* The simple filters never change the size of the data. Specifying options
* for them is optional: if pointer to options is NULL, default values are
* used. You probably never need to specify these options, so just set the
* options pointer to NULL and be happy.
*
* If options with non-default values have been specified when encoding,
* the same options must also be specified when decoding.

* _separately_ for multiple sections of the same executable file,
* and the sections contain cross-section branch/call/jump
* instructions. In that case it is benefical to set the start
* offset of the non-first sections so that the relative addresses
* of the cross-section branch/call/jump instructions will use the
* same absolute addresses as in the first section.
*
* When the pointer to options is NULL, the default value is used.
* The default value is zero.
