XIMEA Image format incorrect after DOWNSAMPLING (Bug #3836)

If I open a XIMA camera and set the downsampling, the retrieved capture frames will have the wrong dimensions.

        // Open the camera:
    cv::VideoCapture cam;
        cv::Mat bufferFrame;
        int columns = 0;

    cam.open(inputName);
        cam.read(bufferFrame); 
        columns = bufferFrame.columns;  //  _Columns value is 2592_

        cam.set(CV_CAP_PROP_XI_DATA_FORMAT, XI_RGB24 );
        cam.set(CV_CAP_PROP_XI_DOWNSAMPLING, ximeaDefaultBinningMode);

        // In the thread loop
    cam.read(bufferFrame);
        columns = bufferFrame.columns;  //  _Columns value is still 2592_

Now, that seems to come from the fact that, in cap_ximea.cpp,

        void CvCaptureCAM_XIMEA::resetCvImage()  // Called from CvCaptureCAM_XIMEA::retrieveFrame()
        {
         ...
        if( (int)image.width != width || (int)image.height != height || image.frm != (XI_IMG_FORMAT)format)
        ...
        }

the validation checks for the identity of the image dimensions (which are the same, since they were updated by the internal CvCaptureCAM_XIMEA::grabFrame() call), but does not check for the identity of the frame dimensions (which have not been changed, and need to).
An easy fix probably would be to add a check of the frame.cols and frame.rows in that condition line.
