// %s - string
// %d,%i - integer
// %f - double
// %o,%O - a JS object.
// %c - style string.
// The output is an array where any object is a separated item, the rest is
// unified in a format string.
// Example if the input is:
// "string: %s, integer: %d, object: %o, double: %d", 's', 1, window, 0.9
// The output will be:
// [ "string: s, integer: 1, object: ", window, ", double: 0.9" ]

// The aStyles array is populated with the style strings that the function
// finds based the format string. The index of the styles matches the indexes
// of elements that need the custom styling from aSequence. For elements with
// no custom styling the array is padded with null elements.
