And will pdfioPageCopy() also be enough if I still put a single input 
page onto the output page but scale and/or crop the page? Will the 
annotations or filled in content also be appropriately scaled, moved, 
and cropped?

So this issue is for solving the above on the level of ipptransform? 
Would it be then not better to have it in PDFio so that it gets re-used 
in libcupsfilters?
