This sounds useful (to the extent that anything in libcucul can be
considered useful, of course). There are a few reasons why we haven't
implemented that yet:
* it changes the canvas size, hence needs reallocation and cannot be
easily done in-place.
* given that character cells are not square, it is not clear to me
whether a source line should be mapped to one or two destination
columns.
* (related to the previous) I wouldn't know what to do with fullwidth
characters.
Anyway, cucul_rotate_left() and cucul_rotate_right() make sense.
