I am using some code

// Rotated text drawing with X.

// Original code:
// Copyright (c) 1992 Alan Richardson (mppa3@uk.ac.sussex.syma) */
//
// Modifications for fltk:
// Copyright (c) 1997 Bill Spitzak (spitzak@d2.com)
// Modifications are to draw using the current fl_font.  All fonts
// used are cached in local structures.  This can get real expensive,
// use "

to rotate fonts in FLTK. This works on my PC with X. I am not sure which 
fonts, it uses though.

It contains the lines

   /* create the depth 1 canvas bitmap ... */
   canvas = XCreatePixmap(dpy, root, boxlen, boxlen, 1);

   /* create a GC ... */
   font_gc = XCreateGC(dpy, canvas, 0, 0);
   XSetBackground(dpy, font_gc, off);

1bpp for fonts should be ok?

I attach them if you don't mind... ;-)
