--- Comment #1 from Adrian Johnson <ajohnson at redneon.com> ---
The format parameter to the image writers defines the pixel format so there is
no need to add the supportNativeMonoRowData() function.

I would suggest adding the data:

 SplashColorMode imageWriterFormat;

to SplashBitmap.h.

In writeImgFile() (line 353), set imageWriterFormat to the format to supply to
writeRow().

ie splashModeMono8 for TiffWriter(TiffWriter::GRAY),
   splashModeMono1 for TiffWriter(TiffWriter::MONO), and 
   splashModeRGB8 for everything else.

Then use imageWriterFormat in writeImgFile() (line 620) to determine the data
format to use for mode = splashModeMono8 or splashModeMono1.
