0030857: Visualization - using one implementation of Text in graphic group

Browse Source 
Graphic3d_Group::Text(...) are obsolete, AddText() should be used instead of these methods.
Graphic3d_Text is a new class for parameters necessary to fill OpenGl_Text. All parameters of Graphic3d_Group::Text() are moved into this class.

OpenGl_TextParam is removed, these fields were moved into Graphic3d_Text.
OpenGl_Text constructors/Init with OpenGl_TextParam parameter were removed. Constructor with Graphic3d_Text should be used instead of it.
Using OpenGl_Text Init() with OpenGl_TextParam should be now replaced on two cases. The first case is setting values into Graphic3d_Text and the second case is calling Reset() after. As example, look at modification in OpenGl_FrameStatsPrs.

@subsection upgrade_740_text Changes in Graphic3d_Text and OpenGl_Text API
Parameters of *Text* in *Graphic3d_Group* are moved into a new *Graphic3d_Text* class. *AddText* of *Graphic3d_Group* should be used instead of the previous *Text*.
The previous code:
~~~~
Standard_Real x, y, z;
theAttachmentPoint.Coord(x,y,z);
theGroup->Text (theText,
Graphic3d_Vertex(x,y,z),
theAspect->Height(),
theAspect->Angle(),
theAspect->Orientation(),
theAspect->HorizontalJustification(),
theAspect->VerticalJustification());
~~~~
should be replaced by the new code:
~~~~
Handle(Graphic3d_Text) aText = new Graphic3d_Text (theAspect->Height());
aText->SetText (theText.ToExtString());
aText->SetPosition (theAttachmentPoint);
aText->SetHorizontalAlignment (theAspect->HorizontalJustification());
aText->SetVerticalAlignment (theAspect->VerticalJustification());
theGroup->AddText (aText);
~~~~
*OpenGl_Text* contains *Graphic3d_Text* field.
*OpenGl_TextParam* struct is removed. Constructor and *Init* of *OpenGl_Text* with *OpenGl_TextParam* are also removed.
Instead of using them, change *OpenGl_Text*.
Please, note, that after modifying *OpenGl_Text*, *Reset* of *OpenGl_Text* should be called.
*FormatParams* of *OpenGl_Text* is replaced by *Text*.
@subsection upgrade_740_prsupdate Presentation invalidation
Historically AIS_InteractiveObject provided two independent mechanisms invalidating presentation (asking presentation manager to recompute specific display mode or all modes):
