Due to the limitations of X there is no standart way provided. You can
only do it "by hand". Render the text to an offscreen pixmap, rotate the
pixmap and then render it to the main window.

For drawing text on drawingareas there is no other way.

I didn't found any. So i learned it the hard way, with the reference and
trial and error. On differnt mailinglists i read that pango isn't for
the app-developer and for the ones who build widgets the reference is
enought ;-)

Not well documented but may be a start; look at the code of the
gtklabel. There you'll find some different pango techniques.
