// DATA
// ----

var gRefSnapshots = {};

// These are the sets of 'order' values that we'll test.
// The first three values in each array are the 'order' values that we'll
// assign to elements a, b, and c (respectively).  The final value in each
// array is the ID of the expected reference rendering.

  // The 6 basic permutations:
  [ 1, 2, 3, "abc"],

  [ 2, 1, 3, "bac"],
  [ 2, 3, 1, "cab"],

  [ 3, 2, 1, "cba"],

  // Test negative values
  [ 1, -5, -2, "bca"],

  // Non-integers should be ignored.
  // (So, they'll leave their div with the initial 'order' value, which is 0.)

  // Decimal values that happen to be equal to integers (e.g. "3.0") are still
  // <numbers>, and are _not_ <integers>.
  //  Source: http://www.w3.org/TR/CSS21/syndata.html#value-def-integer
  // (So, they'll leave their div with the initial 'order' value, which is 0.)
  // (NOTE: We have to use quotes around "3.0" and "2.0" to be sure JS doesn't
  // coerce them into integers before we get a chance to set them in CSS.)
