*
* First page footer content. Corresponds to first printed page.
* The first logical page in the sheet may not be printed, for example, if the print area is specified to
* be a range such that it falls outside the first page's scope.
*
* The first page footer is activated by the "Different First" Header/Footer property for the sheet.
* If this property is not set, the first page footer is ignored.
*
* Creating a first page header or footer sets this property by default, so all you need to do to
* get an first page header or footer to display is to create one. Likewise, if both the first page
* header and footer are usnset, then this property is unset, and the first page header and footer
* are ignored.
