Matrix.equalFast

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

While this function is faster than graphene.matrix.Matrix.equal, it can also return false negatives, so it should be used in conjuction with either graphene.matrix.Matrix.equal or graphene.matrix.Matrix.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
  }
