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.
