Hello? Anyone in there?

> This patch implements the feature request of bug 321350: if a PDF file is viewed, the selection tool offers the new extraction method "vector" which allows to save to a file (PDF, SVG, EPS, PostScript). The crop operation is performed by calling "pdftocairo" with matching arguments. The resulting file contains the original PDF file's content without rendering it to a pixmap.

Alternatively, the code of pdftocairo (as part of poppler) would had to be copied and integrated into Okular increasing the solution's complexity. I am not aware of a similar solution available using poppler-qt4 only. Maybe using a QPrinter printing to PDF would have been an alternative, but again this seemed to be too complex.
