0030537: Visualization - wrapping text in font text formatter

Browse Source 
Font_TextFormatter inherits Standard_Transient, now it is given as a handle in functions.
Graphic3d_Text - extended with Font_TextFormatter to be able to have it filled out of text render. If it is not defined here, the default text formatter of context is used.
OpenGl_Context - has default Font_TextFormatter for rendering OpenGl_Text.
AIS_TextLabel extending with Font_TextFormatter to prepare test case for text wrapping.
Prs3d_Text returns created graphic text to be able to manage it outside.
