Ian Maquignaz
085a131801 Applied '@ref' linking for 3.4 Calib3D parameters and added enum cv::fisheye::CALIB_ZERO_DISPARITY == cv::CALIB_ZERO_DISPARITY == 0x400 == 1 << 10. 
Fisheye test has been updated to use new enum cv::fisheye::CALIB_ZERO_DISPARITY and included CV_StaticAssert(...) to ensure cv::CALIB_ZERO_DISPARITY == cv::fisheye::CALIB_ZERO_DISPARITY.
