// .NAME vtkMatplotlibMathTextUtilities - Access to MatPlotLib MathText rendering
// .SECTION Description
// vtkMatplotlibMathTextUtilities provides access to the MatPlotLib MathText
// implementation.
//
// This class is aware of a number of environment variables that can be used to
// configure and debug python initialization (all are optional):
// - VTK_MATPLOTLIB_DEBUG: Enable verbose debugging output during initialization
// of the python environment.
