Divide by zero

[Fogrunner]

Hello.

First for all, thanks for sharing great code.

I have found some memory crashing case.

When i put the same zero control point , some code makes crashing.

// 2 zero points
qsrc.push_back(cv::Point_<int>(0, 0));
qsrc.push_back(cv::Point_<int>(0, 0));

// 2 zero points
qdst.push_back(cv::Point_<int>(0, 0));
qdst.push_back(cv::Point_<int>(0, 0));

In imgwarp_mls_rigid.cpp

tmpP *= w[k] / miu_r;

Above code makes dividing by zero without handling.

It seems to happen when i put control points which have the same values.
