It worked!. I could still see some drawing-erasing, so I solved it
modifying o_rotate_90 so it accepts two new boolean parameters:
erase_objs, and redraw_objs, which controls the erasing and redrawing of
the objects. This way, no erasing or redrawing is made if not desired.

Yes. As you pointed out, this also happens when hitting the ESC key
after the fist rotation...
The problem is that the list of selected objects is really a list of
pointers to the objects. If we are going to allow operations while
moving/copying, etc, we need to work with a list of selected objects
which are really a copy of the real objects. I'm not sure about how to
deal with this....
