class_docstr: Class that provides a series of GL functions that do not fit
  in the object oriented part of gloo. An instance of this class is
  associated with each canvas.
docstr: Specify multisample coverage parameters
  
  Parameters
  ----------
  value : float
      Sample coverage value (will be clamped between 0. and 1.).
  invert : bool
      Specify if the coverage masks should be inverted.
