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
