* For the functions: new, destroy, duplicate and merge: the following values
* for align are valid:
* * align == NULL (!) represents no solution
* * align->grain_size == 0 represents a single solution
* (align->offset)
* * align->grain_size > 0 represents a set of solutions
*
* These are invalid:
* * align->offset < 0 Note: this gets "normalized"
* * align->grain_size < 0
*
* For the align_* operations, there must be a solution. i.e. align != NULL
* All solutions must be greater than zero.
