Description:
------------
As reported in Bug "#37671 MySQLi extension fails to recognize BIT colums" I have the same problem with a Spatial Column.

The Column coord is a POINT Field.



Reproduce code:
---------------
Here is the Table-Definition:
CREATE TABLE `user` (
 `coord` point default NULL,
) ENGINE=InnoDB

The Test Code:

// $mysqli is an existing db connection

$stmt = $mysqli->prepare("SELECT coord FROM user");
$stmt->execute();
$stmt->bind_result($res);
while ($stmt->fetch() === true ) {
  debug_zval_dump($res);
  var_dump($res);
}
$stmt->close();

Expected result:
----------------
The binary representation of the point

Actual result:
--------------
The Output is the same as the BIT-Field Problem (#37671)
