equal_fast

Checks whether the two given Matrix matrices are byte-by-byte equal.

While this function is faster than equal, it can also return false negatives, so it should be used in conjuction with either equal or near. For instance:

  if (graphene_matrix_equal_fast (a, b))
    {
      // matrices are definitely the same
    }
  else
    {
      if (graphene_matrix_equal (a, b))
        // matrices contain the same values within an epsilon of FLT_EPSILON
      else if (graphene_matrix_near (a, b, 0.0001))
        // matrices contain the same values within an epsilon of 0.0001
      else
        // matrices are not equal
    }

Parameters:

this	a Matrix
b	a Matrix

Returns:

`true` if the matrices are equal. and `false` otherwise
