Export large scale print file + web file

[res56]

@res56

void mousePressed() { 
  saveFrame("balls-#####.png");
   surface.setResizable(true);
   surface.setSize(7200, 9600);
   pdf = (PGraphicsPDF)beginRecord(PDF, "test.pdf");
   endRecord();
   exit();
} 

This code works, only the pdf is empty (but I can open it)
