Stack of frames in horizontal (default) or vertical stack.

The splitters are placed between the neighbouring frames so that they can be resized by the user. When the whole pack is resized, frames are scaled proportionally to their previous size.

When frames are left in pack at destruction time, they will be deleted via local-cleanup.
