//
// Class responsible for handling the writing of multipart images.
//
// Note: Certain attributes are 'common' to all parts. Notably:
// * Display Window
// * Pixel Aspect Ratio
// * Time Code
// * Chromaticities
// The first header forms the basis for the set of attributes that are shared
// across the constituent parts.
//
// Parameters
// headers - pointer to array of headers; one for each part of the image file
// parts - count of number of parts
// overrideSharedAttributes - toggle for the handling of shared attributes.
// set false to check for inconsistencies, true
// to copy the values over from the first header.
// numThreads - number of threads that should be used in encoding the data.
