[mkgmap-dev] Display Zipfile

Hi Gerd Trying to use display/src/test/ZipFile.java to reconstitute a tile .img from the constituents in a .gmap directory tree or extracted from a gmapsupp.img so I could run other display diagnostics I found it was broken, probably due to blocksize optimisation project. I attach a patch that gets it working again and has some comments about how it might be used. Ticker
