- picked or selected objects are now highlighted via owners instead of interactive objects; - support methods for owners were added to AIS_InteractiveContext; - dynamically highlighted owners are now displayed in immediate mode; - selection without opening of local context is enabled by default; - added "-local" key to vselmode command to enable selection in local context; - selection filters are now completely supported in AIS_InteractiveContext; - the idea of differencing of selected items onto current (in interactive context) and selected (local selection) was eliminated; - all calls to "current" were replaced by calls to "selected" in terms of future local context removal; - AIS_InteractiveObject::mySelectionMode was removed; - now each selectable object can define own selection mode for "global" selection of the whole object; - whole object selection mode is 0 by default for all standard interactive objects; - immediate structures are now added to topmost and top layer lists; - added support of drawing immediate structures in different layers; - unused code for immediate mode was removed; - vfeedback and vexport commands now produce correct output for raytrace mode.
