0x13 and 0x10 represent a newline, all PS rips must work with any line
end, i.e. 0x13 is line end, not data. Similarly, 0x04 is job end mark
for PS rip, i.e. it must not appear within a PS file. Using binary
data in EPS is a pain, you must be sure that they are correctly marked
by structure comments, dvips may then treat them corretly. However, PS
printers do not read the structure comments and printing may fail.
