class TEveProjectionManager: public TEveElementList, public TAttBBox


 Manager class for steering of projections and managing projected
 objects.

 Recursively projects TEveElement's and draws axis in the projected
 scene.  It enables to interactivly set TEveProjection parameters
 and updates projected scene accordingly.

Function documentation

TEveProjectionManager(TEveProjection::EPType_e type = TEveProjection::kPT_Unknown)
 Constructor.
~TEveProjectionManager()
 Destructor.
 Destroys also dependent elements.
void AddDependent(TEveElement* el)
 Add el as dependent element.
void RemoveDependent(TEveElement* el)
 Remove el as dependent element.
void UpdateName()
 Updates name to have consitent information with prjection.
void SetProjection(TEveProjection::EPType_e type)
 Set projection type and distortion.
void SetCenter(Float_t x, Float_t y, Float_t z)
 Set projection center and rebuild projected scene.
Bool_t HandleElementPaste(TEveElement* el)
 React to element being pasted or dnd-ed.
 Return true if redraw is needed (virtual method).
Bool_t ShouldImport(TEveElement* el)
 Returns true if element el should be imported.

 Behaviour depends on the value of the fImportEmpty member:
   false - el or any of its children must be projectable (default);
   true  - always import.
void UpdateDependentElsAndScenes(TEveElement* root)
 Update dependent elements' bounding box and mark scenes
 containing element root or its children as requiring a repaint.
TEveElement* ImportElementsRecurse(TEveElement* el, TEveElement* parent)
 If el is TEveProjectable add projected instance else add plain
 TEveElementList to parent. Call the same function on el's
 children.

 Returns the projected replica of el. Can be 0, if el and none of
 its children are projectable.
TEveElement* ImportElements(TEveElement* el, TEveElement* ext_list = 0)
 Recursively import elements and apply projection to the newly
 imported objects.

 If ext_list is not 0 the new element is also added to the list.
 This simplifies construction of complex views where projected
 elements are distributed into several scenes for optimization of
 updates and rendering.

 Returns the projected replica of el. Can be 0, if el and none of
 its children are projectable.
TEveElement* SubImportElements(TEveElement* el, TEveElement* proj_parent)
 Recursively import elements and apply projection to the newly
 imported objects.

 The proj_parent argument should be a projected replica of parent
 of element 'el'. This allows to insert projected children of
 a given element when they are added after the projection has
 been already performed on the parent.
 This is called from TEveElement::ProjectChild().

 Returns the projected replica of el. Can be 0, if el and none of
 its children are projectable.
Int_t SubImportChildren(TEveElement* el, TEveElement* proj_parent)
 Recursively import childer elements of el and apply projection
 to the newly imported objects.

 The proj_parent argument should be a projected replica of
 element 'el'. This allows to insert projected children of
 a given element when they are added after the projection has
 been already performed on the parent.
 This is called from TEveElement::ProjectChild().

 Returns the projected replica of el. Can be 0, if el and none of
 its children are projectable.
void ProjectChildrenRecurse(TEveElement* el)
 Project el (via TEveProjected::UpdateProjection()) and recurse
 through el's children.
 Bounding-box is updated along the recursion.
void ProjectChildren()
 Project all children recursively, update bounding-box and notify
 TEveManger about the scenes that have been changed.
void ComputeBBox()
 Virtual from TAttBBox; fill bounding-box information.

 The bounding-box information is kept coherent during addition of
 projected elements and projection parameter updates. This is
 called only in case the manager has not been populated at all.
