This function renders the detail view of a pdf page. This page consists of the pdf preview with the text highlighted in the respective color and the table with more details about every sentence. To highlight the text parts in the pdf preview, colored+transparent HTML-divs get rendered over the canvas with the respective position and size. Finding the correct position proved a difficult task, as sentence might span multiple lines and start/end at the middle of the page. As PDFjs only returns coordinates of blocs of texts and not the actual coordinates of sentences, some calculations must be done. A sentence might begin/end in the middle of a bloc, span across multiple blocs or one bloc might even contain multiple sentences. This function handles all these scenarios so that the overlayed divs are positioned correctly.
