/**
* Circularly shifts the elements of a double-precision floating-point strided array by a specified number of positions using alternative indexing semantics.
*
* ## Notes
*
* - This implementation is based on the "trinity rotation" (a.k.a., conjoined triple reversal) algorithm introduced in <https://github.com/scandum/rotate/tree/6d0d2d56d10454def027e35921890200b45fe82c>, by Igor van den Hoven.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {integer} k - number of positions to shift
* @param {Float64Array} x - input array
* @param {integer} strideX - stride length
* @param {NonNegativeInteger} offsetX - starting index
* @returns {Float64Array} input array
*
* @example
* var Float64Array = require( '@stdlib/array/float64' );
*
* var x = new Float64Array( [ 1.0, 2.0, 3.0, 4.0, 5.0, 6.0 ] );
*
* dcircshift( x.length, 2, x, 1, 0 );
* // x => <Float64Array>[ 5.0, 6.0, 1.0, 2.0, 3.0, 4.0 ]
