More DPI options, and a Note about which are best for Print and Digital

Having 72, 96, 108, 300, and 600 DPI options would be great; along with a note like:
72: Standard Web Quality
96: Medium Quality Digital
108: High Quality Digital
300: Medium Quality Print
600: High Quality Print

Also, for video, limiting it only to the 72, 96, and 108ppi options should solve some issues
