Demo 1: (for iPad Air and iPad Mini 2)
- The images have a size with an odd height - 512 x 321 pixel.
- The chroma will be subsampled (blurred and shifted red colors).
- At the bottom one 1px row will be missing (because of the odd height).
- The image will be stretched vertically (by this missing 1px row).
- Test this on an iPad Air or iPad Mini 2, an iPad 3 will be fine here.
