== Overview ==

Users need to be able to align frames.  Alignment is done via a HUD to the current selection.  Alignment is only viable when the selection contains more than one item.  See the related section of this task for the multi-select task, which should be done before this task.

Alignment should be undoable, and may rely on the PRO_CHANGE tasks (see related).  Alignment via the sides and centers of objects is a good start.  Later we can add distribution if deemed necessary.

== Task requirements ==

 * Add a halo for alignment to frames if there is more than one frame selected
 * The halo's hud will have buttons for choosing the alignment (see implementation idea)
 * Alignment operations should be undoable (might be blocked by PRO_CHANGE work)

== Task result ==

The result of this task is code

== Implementation idea ==

 * Use the [wiki:PAGE_ELEMENT_MULTI_SELECT_R0] changes to determine if there is more than one item selected
 * Due to the fact that we don't have grouping yet, put the alignment halo on the last frame added to the selection (this may be part of [wiki:PAGE_ELEMENT_MULTI_SELECT_R0] that I missed)
 * Support the following alignments:
  * Align left sides
  * Align top sides
  * Align bottom sides
  * Align right sides
  * Align vertical centers
  * Align horizontal centers

 * The first frame in the selection is the master frame in terms of which frame to align to
