Helper functions for manipulating phase patterns.

Functions

`convert_blaze_radius`	Helper function for scalar unit conversions.
`convert_blaze_vector`	Helper function for vector unit conversions.
`fit_3pt`	Fits three points to an affine transformation.
`format_2vectors`	Validates that an array of 2D vectors is a `numpy.ndarray` of shape `(2, N)`.
`imprint`	Imprints a region (defined by `window`) of a `matrix` with a `function`.
`lloyds_algorithm`	Implements Lloyd's Algorithm on a set of `vectors` using the helper function `voronoi_windows()`.
`lloyds_points`	Implements Lloyd's Algorithm without seed `vectors`; instead, autogenerates the seed `vectors` randomly.
`pad`	Helper function to pad data with zeros.
`print_blaze_conversions`	Helper function to understand unit conversions.
`shift_grid`	Returns a copy of a coordinate basis `grid` with a given `shift` and `transformation`.
`smallest_distance`	Returns the smallest distance between pairs of points under a given `metric`.
`unpad`	Helper function to unpad data.
`voronoi_windows`	Returns boolean array windows corresponding to the Voronoi cells for a set of vectors.
`window_slice`	Get the slices that describe the window's view into the larger array.
`window_square`	Find a square that covers the active region of `window`.
