Trick: tilted "glissando" text

[Antti Kaihola]

I'd like to share a postscript hack I used to print the "gliss." text
under a scale passage and tilt the text according to the angle of the
scale.

You can adjust according to your layout the
- angle (here -15 degrees)
- offset (5 -2)
- scale (12.0)
- font (\CMTI12)
- text (gliss.)

Please point out if this can be done in a more elegant way. I'm not a
PostScript guru or LilyPond expert, so I don't really understand what
I'm doing... :)
