I do not have the backend done, I haven't even started on it.  I want to
get 0.92 out soon (once the sudden spate of isinf/finite problems is over,
I will release 0.92pre1), and only after that is done will I look at
rotation.  Sorry, but it'd delay the release too much to implement it now.

Yeah, those would be good as menu items.

Since I plan to implement rotate by having a transformation matrix (giving
us scaling and flipping at the same time), the programmed objects would
suddenly also be flippable.

With [counter]clockwise, there is no discussion what way it is.  Degrees
could go either way, it's usually clockwise, but not always.

That is probably true.
