Calculate dependent area based on distortion model rather than using 15% of image resolution for this. Some assumptions here: - We're assuming real-life camera calibration is used here - Maximal undistortion delta would be achieved on frame boundary - Distortion fully goes inside frame This makes it possible to approximate margin for distortion by checking undistortion delta across frame boundary and use it for dependent area of interest. We do not use any formula-based equation here because we're likely support other distortion models and in that case it'll be stupid to try detecting formula here.
