patch to add a pdftops -r # option to set the splash dpi resolution

When pdftops -level1 or -level1sep finds a transparency or a color image mask, it uses splash to rasterize the image.  PSOutputDev.cc currently uses a hard-coded value of 300 dpi.  This patch allows you to set a different value on the command line.  The hard-coded value of 300 dpi is a good compromise between resolution and file size, but I am printing on a high-resolution device that supports over 1000 dpi, and rasterizing at 300 dpi degrades some details in my images.  Conversely, someone worried about file size might want to select a lower resolution.

The description is wrong, it's not just for level1 files, there are other ocassions in which rasterization might trigger (as you can see in PreScanOutputDev). Can you fix that?

Updated -r patch

Updated patch with more accurate information in the pdftops help message for -r and in the pdftops man page.
