// ODAdjustColor()
//
// Used for playback on 4bpp devices.  We convert colors that are 'close'
// to VGA to their VGA equivalents.
//
// This function tries to find a close match in the VGA color set for a
// given input color.  Close is defined as follows: each color element
// (red, green, blue) must be within 7 of the corresponding element in a
// VGA color, without wrapping.  For example
//
// - 0xc7b8c6 is 'close' to 0xc0c0c0
//
// - 0xf8f8f8 is 'close' to 0xffffff
//
// - 0xff0102 is not 'close' to 0x000000, but is 'close' to 0xff0000
//
// Closeness is determined as follows:
//
// - for each entry in the table s_odVGAColors
//   - ADD the addMask to the color
//   - AND the result with the andMask
//   - if the result equals the testMask, this VGA color is close match
//
// Think about it.  It works.
