The implementations of CvMat::get/put(i,j) and CvMat::get/put(i, j, k) are wrong

[GoogleCodeExporter]

In opencv_core.java, in class CvMat.

The matrix element offset calculation used in the get/put(i, j) and get/put(i, 
j, k) incorrectly assumes that the step() method does not include the memory 
taken by the channels into the result. This produces IndexOutOfBoundsException 
when trying to access the multichannel matrix.

Currently the expression is "(i*step()/elemSize() + j)*channels()", it should 
be "i*step()/elemSize()+j*channels()" instead.

What steps will reproduce the problem?
1.Load a RGB image into a matrix with cvLoadImageM().
2.Try accessing the bottom right pixel.

What is the expected output? What do you see instead?
Expected output is a value of one of the channels. An IndexOutOfBoundsException 
is thrown instead.

What version of the product are you using? On what operating system?
Version 2012021. On Windows XP 32.
