Bug #705035 "PCLm mode neds 8-bit Grayscale mode"
Add a new device 'pclm8' which outputs in DeviceGray, for use with
'WiFi Direct Print' enabled monochrome printers.
While the printer is supposed to be able to accept RGB, and print to
gray, it's quicker to send Gray instead of RGB when we know it is
required.
