Description

When using findCirclesGrid with a pattern with an even number of rows, the points are not detected in the correct order.
If the number of rows is odd, the order is correct.
This is important in order to establish image-object point correspondences well.

At least it should be indicated in the documentation that this restriction is necessary for the function to work as expected.
Ideally it should be fixed so that any number of rows works correctly
