Description:
 def _createoddslicespec(bounds,scs,min_matrix_radius):
 """ Create the 'odd' Slice that best approximates the specified sheet-coordinate bounds. The supplied bounds are translated to have a center at the center of one of the sheet's units (we arbitrarily use the center unit), and then these bounds are converted to a slice in such a way that the slice exactly includes all units whose centers are within the bounds (see boundsspec2slicespec()). However, to ensure that the bounds are treated symmetrically, we take the right and bottom bounds and reflect these about the center of the slice (i.e. we take the 'xradius' to be right_col-center_col and the 'yradius' to be bottom_col-center_row). Hence, if the bounds happen to go through units, if the units are included on the right and bottom bounds, they will be included on the left and top bounds. This ensures that the slice has odd dimensions. """
