VisualModelImpl
---------------

Context: Sofa.Component.Visual

Generic visual model. If a viewer is active it will replace the VisualModel alias, otherwise nothing will be displayed.

Data:
 - name : object name
 - printLog : if true, emits extra messages at runtime.
 - tags : list of the subsets the objet belongs to
 - bbox : this object bounding box
 - componentState : The state of the component among (Dirty, Valid, Undefined, Loading, Invalid).
 - listening : if true, handle the events, otherwise ignore the events
 - enable : Display the object or not
 - position : Vertices coordinates
 - restPosition : Vertices rest coordinates
 - normal : Normals of the model
 - initRestPositions : True if rest positions must be initialized with initial positions
 - useNormals : True if normal smoothing groups should be read from file
 - updateNormals : True if normals should be updated at each iteration
 - computeTangents : True if tangents should be computed at startup
 - updateTangents : True if tangents should be updated at each iteration
 - handleDynamicTopology : True if topological changes should be handled
 - fixMergedUVSeams : True if UV seams should be handled even when duplicate UVs are merged
 - keepLines : keep and draw lines (false by default)
 - vertices : vertices of the model (only if vertices have multiple normals/texcoords, otherwise positions are used)
 - texcoords : coordinates of the texture
 - tangents : tangents for normal mapping
 - bitangents : tangents for normal mapping
 - edges : edges of the model
 - triangles : triangles of the model
 - quads : quads of the model
 - vertPosIdx : If vertices have multiple normals/texcoords stores vertices position indices
 - vertNormIdx : If vertices have multiple normals/texcoords stores vertices normal indices
 - filename :  Path to an ogl model
 - texturename : Name of the Texture
 - translation : Initial Translation of the object
 - rotation : Initial Rotation of the object
 - scale3d : Initial Scale of the object
 - scaleTex : Scale of the texture
 - translationTex : Translation of the texture
 - material : Material
 - putOnlyTexCoords : Give Texture Coordinates without the texture binding
 - srgbTexturing : When sRGB rendering is enabled, is the texture in sRGB colorspace?
 - materials : List of materials
 - groups : Groups of triangles and quads using a given material

Links:
 - context : Graph Node containing this object (or BaseContext::getDefault() if no graph is used
 - slaves : Sub-objects used internally by this object
 - master : nullptr for regular objects, or master object for which this object is one sub-objects
 - topology : link to the topology container
