/**
* Sifts a value down into a strided min-heap.
*
* ## Notes
*
* - The function assumes that the subtrees rooted at the children of `index` already satisfy the min-heap property and only the value being sifted may violate the min-heap invariant.
* - The min-heap algorithm is sensitive to the presence of `NaN` values. Since `NaN` comparisons always return `false`, if `NaN` values are present in the input array, the results may be unpredictable.
*
* @param {PositiveInteger} N - number of indexed elements
* @param {NonNegativeInteger} index - logical index at which to begin sifting
* @param {number} value - value to place into the heap
* @param {NumericArray} x - heap storage array
* @param {integer} strideX - stride length
* @returns {NumericArray} heap storage array
*
* @example
* var x = [ 7.0, 2.0, 3.0, 4.0, 5.0 ];
*
* gminheapSiftDown( 5, 0, 7.0, x, 1 );
* // x => [ 2.0, 4.0, 3.0, 7.0, 5.0 ]
