/* This function is only called if the user selects the "Increase drive size" AND
 * "Enlarge partition" options. It increases the drive size by inserting unallocated
 * sectors into the disk image immediately after the current boot partition, and
 * then calls on the filesystem handler which owns that partition to "grow" into
 * the available space.
 *
 * Note that this function creates a modifiable Copy-On-Write (COW) overlay on top
 * of the original source drive, hence this function passes out a new HVDDR handle
 * which should henceforth be used instead of the handle passed in.
 *
 * If "Enlarge partition" is not set but "Enlarge disk" is, then an pre-existing
 * (simpler) function is called to expand the disk.
