Encapsulated xml3d view after component update into separate function and added check if the xml3d view is already available
Workarounded mesh replacement to only support visibility changes. Removing the old XML3D node causes crashes for models that reference to data nodes with their scene graph
Divided addMesh procedure of scenemanager in separate functions per created xml3d element
Mesh groups are now created also when they are initially invisible. Their correct visibility state will be set at the end of the creation procedure
Loading an external XML3D document now also copies the definitions to a distinct def tag instead of keeping it in the main group element
Def Section is now copied from the parsed XML3D Doc
Xflow animations are now parsed from the copied mesh definitions
Removing an entity now removes the group first before removing potentially referenced elements
Removing an entity now also removes its defintions
Better comment to explain the existing issue
Avatars are created visible from the beginning as workaround for geometry remove-and reinsert- bug
Merge branch 'geometry_workaround' into develop
