On windows, using the display device on files with rops in gives incorrect
results. For example:

 main/obj/pcl6.exe -sDEVICE=display simple.pcl

I first noticed this using -sDEVICE=display -dDisplayFormat=16#20101 to try and
reproduce what I saw using -sDEVICE=pbmraw and then loading it into xli on

On windows, debug and release builds are different (but both wrong).

Attached is a cut down pcl file that shows the problem:

 Esc * v 1 N         Source Transparency = Opaque
 Esc * l 17 0        Rop13 = 17
