buffer size too small

[Yusuke Suzuki]

For large size image, EDLines buffer sizes are some times too small and constructor overruns.

In my use, I've fixed the lines as bellow.

ED_Lib/EDLines.cpp

Line 24 in 745472f

 // Temporary buffers used during line fitting 

    size_t buffer_size = 1; 

    for (int segmentNumber = 0; segmentNumber < segmentPoints.size(); segmentNumber++) {
        auto segment_size = segmentPoints[segmentNumber].size();
        buffer_size = std::max(buffer_size, segment_size);
    }    

    double *x = new double[buffer_size];
    double *y = new double[buffer_size];

I have also encountered the same problem. @YusukeSuzuki your suggestion works, thanks!
