// When "PDFViewerApplication.initialize" is executed it overwrites the value of
// "PDFJS.workerSrc", so the custom initialization has to be executed after
// that. As "PDFViewerApplication" does not provide any hookable point for
// custom initialization in its initialization routine a dirty hack has to be
// used.
//
// When "vendor/pdfjs/web/viewer.js" is parsed at the end it calls
// "PDFViewerApplication.initialize" (either directly or as a "DOMContentLoaded"
// event handler), and "PDFViewerApplication.initialize" sends an asynchronous
// XHR request to initialize the locales, which causes the execution flow to
// continue with the next script or the next "DOMContentLoaded" handler. Thanks
// to this "initializeCustomPDFViewerApplication" can be executed at that point
// by parsing "js/workersrc.js" after "vendor/pdfjs/web/viewer.js" and either
// calling it directly or adding it as a "DOMContentLoaded" event handler (using
// the same conditions as in "vendor/pdfjs/web/viewer.js").
