Crop settings

16:9 screens are probably the majority of devices these days, and I'd like to suggest a few easily-selectable options for playback:

1) "16:9 screen?" to immediately appear underneath "Default" in the Video > Crop drop-menu. When selected, the following occurs:

* Video with a source display ratio higher than 2.21:1 will be cropped to 2.21:1
* Video with a source display ratio between 1.65:1 and 1.9:1 will be cropped to 16:9
* Video with a source display ratio lower than 16:10 will be cropped to 16:10

-- These result in quite noticeable viewing area increases for 95% of television and movie source material on 16:9 monitors while not cropping off "too much" from a subjective perspective. It will cover all of the following: 1.37:1 (silent film), 4:3 (television and Golden Age Hollywood), 1.66:1 (European film), 2.39:1 (Hollywood standard widescreen), and 1.85:1 (1960s-1980s film), with a little wiggle-room given for "rip" cropping. The large majority of video that most people watch from any source falls within these ranges.

2. Letter-boxed "black-bars" will be auto-sensed and auto-cropped, even from within the context of other selected crop settings (such as the one proposed above), with said letter-box cropping occurring BEFORE "16:9 screen?" kicks in. All optical-drive raw video files (whether DVD or Blu-ray) are letterboxed to some degree. (Even if anamorphic, there's still at least several pixel's worth of trim at the top and bottom, and sometimes on either side, and this black-bar trim usually isn't perfectly black, but is instead dark, dark gray and often contains grain.)

3. Have crop-settings appear in the right-click list during playback. (In fact, I think the whole Video menu, complete with sublists, should appear there.)
