it is now possible to customize default highlight attributes like *Display Mode* and *ZLayer*, which previously could be defined only on Object level.
* Properties *Prs3d_Drawer::HighlightStyle()* and *Prs3d_Drawer::SelectionStyle()* have been removed.
Instead, *AIS_InteractiveObject* now defines *DynamicHilightAttributes()* for dynamic highlighting in addition to *HilightAttributes()* used for highlighting in selected state.
Note that *AIS_InteractiveObject::HilightAttributes()* and *AIS_InteractiveObject::DynamicHilightAttributes()* override highlighting properties for both - entire object and for part coming from decomposition.
This includes Z-layer settings, which will be the same when overriding properties through AIS_InteractiveObject, while *AIS_InteractiveContext::HighlightStyle()* allows customizing properties for local and global selection independently
(with Graphic3d_ZLayerId_Top used for dynamic highlighting of entire object and Graphic3d_ZLayerId_Topmost for dynamic highlighting of object part by default).
* The following protected fields have been removed from class *AIS_InteractiveObject*:
- *myOwnColor*, replaced by *myDrawer->Color()*
- *myTransparency*, replaced by *myDrawer->Transparency()*
