// Even after moving creation of the unallocated space within this new extended
// partition to here after the above alignment adjustment, the boundaries of the
// extended partition may be further adjusted by snap_to_alignment(). However the
// UI when creating logical partitions within this extended partition will use the
// boundaries as defined now by this unallocated space. Hence boundaries of
// logical partitions may be wrong or overlapping.
//
// Test case:
// On an empty MSDOS formatted disk, create a cylinder aligned extended partition.
// Then create a default MiB aligned logical partition filling the extended
// partition. Apply the operations. Creation of logical partition fails with
// libparted message "Can't have overlapping partitions."
//
// To fix this properly all the alignment constraints need to be applied here in
// the dialogs which create and modify partition boundaries. The logic in
// snap_to_alignment() needs including in it. It will need abstracting into a set
// of methods so that it can be used in each dialog which creates and modified
// partition boundaries.
