When a layout has been changed the fullBounds are set to nil. This indicates that the layout needs to be recomputed and is done in the next cycle when layouts are calculated.

layoutChanged
	| layout |
	fullBounds ifNil:[^self]. "layout will be recomputed so don't bother"
	fullBounds := nil.
	layout := self layoutPolicy.
	layout ifNotNil:[layout flushLayoutCache].
	owner ifNotNil: [owner layoutChanged].
	"note: does not send #ownerChanged here - we'll do this when computing the new layout"
