Ok, we are getting the problem. :-)
you see the 3th solution are very difficult. not really good.
the first a little too much minimum ( ;-) )

for the second. (my proposal) we can make a little best allowing to
enter data in a xx:yy way. but this probably need to code a command:
 a setratio xx:yy  to set the map.ratio. If your think this is a ok way,
we can begin with the actual proposal. then i will work in a new patch
to create a more nice setratio  command. you will wait some weeks.
