i think it makes sense. we have -flip and -vf flip.

do you think other vo's can handle rotating osd as well?
-flip does not flip osd. maybe we should make a note of that in the
manual. is -flip done in vo or decoder? i mean is it faster/slower
than -rotate ? would it make sense to make flip an alias of -rotate 2 ?

how about
+Rotate display by 0 (0), 90 (1), 180 (2) or 270 (3) degrees.

i remember long ago trying to put -vf rotate=270 ... and having it work
based on some bug or other.

i ust like to make things complicated. :P
