I have not tested this yes but after a few test found out that using 
directly rect returned by [PDFSelection boundsForPage: ()] is not 
possible. However first going through NSIntegralRect on the result of 
[PDFSelection boundsForPage: ()]  leads to correct behavior. To me 
this looks like an inconsistency in the API and I will enter a bug

Will do.
