- "compress" parameter - turns on compression. This does not mean compressed
  images can be decoded; it is only for development purposes at the moment.
- "testpat" parameter - enables color bar testpattern. Does not work correctly.
- Added 160x120 mode lines to mlist. Does not work yet.
- Added code to convert Y data directly to "black-and-white" RGB data. Useful
  for compression experimentation. Enable with #define OV511_FORCE_MONO and
  #define OV511_DUMPPIX
- VIDEO_PALETTE_YUYV supported; same as YUV422. Still not parsed correctly.
- Removed useless settings from i2c regval structs; i.e. reg 0x05
- OV6620 sensor detection and initialization; Image is garbled though.
- Added detection for Intel Play Me2Cam. (ID is 0x0813:0x0002)
- ov511.h: maxwidth and maxheight added to struct usb_ov511. Sensor specific.
- ov511.h: Added i2c slave IDs for OV6620
- ov511.h: Added SEN_OV6620 to sensor enum
- ov511.txt: Updated
