I added the 'mirror' option to the map swipe tool (r54232). It was
much easier than to implement it for map displays.

mirror mode would be absolutely useful for the georectifier...

it's more complicated there because it's needed to reproject the
region I think. Anyway, georectifier needs refactoring first...

MarkusM has already implemented mirror mode in the georectifier: http://trac.osgeo.org/grass/ticket/1669#comment:2

maybe you are talking about different things? I know that georectifier
can synchronize the displays at one moment but they are not linked
permanently or at least I don't know about it.

This is correct, there is no automagic syncronization in the
georectifier, you need to click a button to sync the displays. This is
because syncing in the georectifier works only if the minimum number
of GCP's is active, which is in turn needed to translate coordinates.
Translating coordinates is not needed for the mirror tool, here
syncing can be done instantly. In the georectifier, the chunk of code
of interest is the syncing of the displays, not the translation of the
coordinates.
