- Fixed invalid presentation of dimension highlight. - Fixed bug on switching between selection modes. Individual sensitive entities generated for each selection mode. - Revised selection: AIS_DimensionSelectionMode enumeration added, redundant AIS_DimensionDisplayMode is removed. - Revised entity owner usage: used standard SelectMgr_EntityOwner for neutral selection, AIS_DimensionOwner for "line", "text" selection modes. - Made arrows selectable. - Got rid of predefined arrow angle. The arrow angle is now taken from dimension aspect. - The 3D text is now centered by bounding box for better alignment.
