kgv a174a3c54f 0023457: Slow text rendering
Added class Font_FTFont wrapper over FreeType face

Unify collections methods NCollection_Array1, NCollection_Sequence, NCollection_Vector:
declare Upper, Lower, First, Last, ChangeFirst, ChangeLast methods for all these collections.

Added method NCollection_DataMap::Find() with check key is bound + retrieve value within single call interface.

OpenGl_Context::ReleaseResource() method now supports lazy release of shared resources.

Added class OpenGl_Font which implements textured fonts support.
Added class OpenGl_TextFormatter for text formatting using OpenGl_Font.

OpenGl_Text was redesigned to use OpenGl_FontFormatter.

OpenGl_FontMgr class was removed.
All methods related to text rendered removed from OpenGl_Display class.

OpenGl_Trihedron and OpenGl_GraduatedTrihedron classes were redesigned
to use OpenGl_Text.

OpenGl_PrinterContext instance was moved to OpenGl_GraphicDriver fields
(eliminated usage of global instance).

Added test cases into 3rdparty/fonts grid to check different font styles
and perform FPS tests (no automated results - requires manual analysis
or snapshots comparisons).

Removed unused CSF_FTGL dependency.
OpenGl_Text::setupMatrix - do not apply floor for myWinZ
