So we have something like:

```
//...
    for(i=0;i<out->size;i++)
    {
        CvPoint pt1 = { out->values[ i * out->dim + 0 ], out->values[ i * out->dim + 1]};
        CvPoint pt2 = { out->values[ i * out->dim + 2 ], out->values[ i * out->dim + 3 ] };
        cvLine(destination, pt1, pt2, CV_RGB(240, 255, 255), 1, CV_AA,0);
    }
//...

```

performed 24 times per second for something like 200 lines. Do we need to delete CvPoint's and how to do it?
