The the space used for a given cell area type. This is used to calculate positioning for other cell areas.

Parameters:

area - The cell area for which the offset is required.

type - The type of area. We can't just get this from the cell area because it might be null.

initialOffset - An initial value to be added to the offset.

pref - If true, use the preferred size, otherwise use the minimum size.

Returns:

The offset of the CellArea.

setLayoutOffset
