function getVectorLength( count, vectorLength = 4 ) {

	const strideLength = getStrideLength( vectorLength );

	const floatLength = strideLength * count;

	return getFloatLength( floatLength );

}
Given the count of vectors and their vector length, this function computes
a total length in bytes with buffer alignment according to STD140 layout.

@function
@param {number} count - The number of vectors.
@param {number} [vectorLength=4] - The vector length.
@return {number} The padded length.
