It should _not_ mirror about the cursor position, because this would move 
the component somewhere "off grid". This kind of cursor dependend rotate 
and mirror behavior already puts me off in gschem. Use the origin of the 
footprint, which is pin 1 or the centroid in most cases.

Don't guess, but define both actions. Use a modifier key to tell which 
flip will be done. Some users will prefer X flips, some will like Y flips 
better. No heuristics will get this right in every case. It would make me 
feel uneasy if the GUI errs while guessing. Please let the basic actions  
be as simple and reliable as possible.
