Python2: Pass native int to `cv2.putText` color
Python2: Pass native int to `cv2.putText` color

`from builtins import *` means that `int` is actually
`future.types.newint.newint`, which subclasses Python 2's `long` rather
than `int` (in Python 3 there is no separate `long` type).

`cv2.putText` raises "TypeError: Scalar value for argument 'color' is
not numeric" -- because it's a tuple of newints, not native ints.

| Code                          | Return type on Python 2 | Python 3 |
|-------------------------------|-------------------------|----------|
| int(...)                      | newint                  | int      |
| future.utils.native(int(...)) | long                    | int      |
| <long|int>.__int__()          | int                     | int      |
