[gl2ps] rotated text in ps

[Shai Ayal]

Hi

At last, after so many help requests, I have a small contribution -- 
rotated text in ps output. Actually, I just figured out the ps code, not 
the changes needed in gl2ps to implement it. just replace the /S macro with

/SR { gsave FC translate 0 0 moveto rotate show grestore } BD

which now shows rotated text:

(rotated) -45 100 25 10 /Helvetica SR

All the other "/S??" macros need to be altered accordingly. Tell if you 
like the idea.
