Detailed Description

Default implementation of vtkTextRenderer.

Default implementation of vtkTextRenderer using vtkFreeTypeTools and vtkMathTextUtilities.

Warning: The MathText backend does not currently support UTF16 strings, thus UTF16 strings passed to the MathText renderer will be converted to UTF8.
