    Defer matplotlib initialization for text rendering. · bdf3b4c2
    David C. Lonie authored
    Rather than querying for matplotlib when
    vtkMatplotlibMathTextUtilities is constructed, check only when
    the library is needed. This saves some start up time for e.g.
    ParaView when mathtext is not used.
    
    Some additional changes are required due to a change in behavior:
    vtkMatplotlibMathTextUtilities::New() used to return NULL when
    matplotlib was not found to signal that mathtext was unavailable.
    The vtkMathTextUtilities::IsAvailable() virtual method has been
    added to allow querying of the availability, now that New() can
    return a valid object when matplotlib is unavailable.
