Dump bitmap images from sensor to a given directory

[marshally]

Functionality should be similar to OpenNI's BackRecorder sample.

Command line options are:

• -d, --depth-bitmap=#{filename}
• -i, --rgb-bitmap=#{filename}
• -f, --frames-to-keep=0,1,2,3,4,5,10,15,30,60,120,180
  • working backwards from the end of the array, always keep the newest frame whose number is greater than the current keep number
• -v, --vga resolution
• -q, --qvga resolution

Should respect -r framerate parameter

Hrm ... that BackRecorder sample isn't quite going to do it. That dumps to OpenNI's mysterious *.oni format. I'm searching for something that will drop the image to a bmp or png.

These classes look a bit more promising:
