Update CameraRaw/Lightroom to work with ultra hi-res images > 512MP or 65K pixels

With cameras continuing to increase in megapixel count, it would be nice to natively have CameraRaw/Lightroom be able to work with images over 512MP or 65,000 pixels long. I understand some limitations are with the jpg file format, but when it comes to TIFF or PSB, having native support in LR would be greatly appreciated.
