Functions
void	mfem::CreateVTKElementConnectivity (Array< int > &con, Geometry::Type geom, int ref)
	Create the VTK element connectivity array for a given element geometry and refinement level.
void	mfem::WriteVTKEncodedCompressed (std::ostream &os, const void *bytes, uint32_t nbytes, int compression_level)
	Outputs encoded binary data in the base 64 format needed by VTK.
int	mfem::BarycentricToVTKTriangle (int *b, int ref)
	Return the VTK node index of the barycentric point b in a triangle with refinement level ref.
const char *	mfem::VTKByteOrder ()
	Determine the byte order and return either "BigEndian" or "LittleEndian".
template<typename T >
void	mfem::WriteBinaryOrASCII (std::ostream &os, std::vector< char > &buf, const T &val, const char *suffix, VTKFormat format)
	Write either ASCII data to the stream or binary data to the buffer depending on the given format.
template<>
void	mfem::WriteBinaryOrASCII< uint8_t > (std::ostream &os, std::vector< char > &buf, const uint8_t &val, const char *suffix, VTKFormat format)
	Specialization of WriteBinaryOrASCII for uint8_t to ensure ASCII output is numeric (rather than interpreting val as a character.)
template<>
void	mfem::WriteBinaryOrASCII< double > (std::ostream &os, std::vector< char > &buf, const double &val, const char *suffix, VTKFormat format)
	Specialization of WriteBinaryOrASCII for double.
template<>
void	mfem::WriteBinaryOrASCII< float > (std::ostream &os, std::vector< char > &buf, const float &val, const char *suffix, VTKFormat format)
	Specialization of WriteBinaryOrASCII<T> for float.
void	mfem::WriteBase64WithSizeAndClear (std::ostream &os, std::vector< char > &buf, int compression_level)
	Encode in base 64 (and potentially compress) the given data, write it to the output stream (with a header) and clear the buffer.
