// given in a system where the image has dimensions given by AFImageWidth and
// AFImageHeight, and 0,0 is the image center. The direction of the Y axis
// depends on the camera model, with positive Y upwards for EOS models, but
// apparently downwards for PowerShot models.

// the number of AF points. Iterate through the array one byte at a time, generally

// For these, read specific subsequent bytes from the array based on the tag type. The
