In theory if there already is a user-provided gs (which doesn't output points) then the emulation code doesn't really apply. But I don't really know this code (other than knowing this is pretty tricky stuff...).</pre> </div> <hr> You are receiving this mail because: <ul> <li>You are the QA Contact for the bug.</li> <li>You are the assignee for the bug.</li> </ul> </body> </html>
