That would be very useful!

I am using OpenMap projection together with jts[1] to buffer[2] a lat/
lon geometry with a number of meters or nautical miles. I project the
geometry from lat/lon to x/y, use jts to buffer and then project back
to lat/lon. With the correct scale value, the precision is ok, but
using double would not hurt..
