layers when passed an array of layers instead of a single layer with the constructor. This changeset also introduces a new layer type, Layer.Vector.RootContainer, which will be set as the topmost layer by the SelectFeature control and collect the svg/vml/canvas roots of multiple vector layers. r=crschmidt (closes #1666) git-svn-id: http://svn.openlayers.org/trunk/openlayers@9116 dc9f47b5-9b13-0410-9fdd-eb0c1a62fdaf
