def write_secondary_postScript(primitive, functionName, writefile):
'''
takes a primitive, a description string. converts it to js readable data
input: primitive ( a joined list with raw commands )
input: the name of the current function. (each graphical element)
input: writefile, is the file we are writing to.
output: straight to file.
i'm not sure what is up with the coordinate system, it's not something i've
been able to find any useful information on. Applying assumptions seems a little
zealous. It seems like, if a primitive doesn't havea a fillColour, that unmodified
point coordinates are ok.
