The unit for Vicgrid94 is a metre. The pixelSize is a tricky one: 25.4/96
expressed in metres is the value above. For whatever reason (I am sure
somebody can explain that) the geowebcache default is 0.28 mm per pixel,
which would equate to 90.174 pixels per inch on a screen. The scale values
above are 8M, 4M, 2M, 1M, 500K, 250K, 100K, 50K, 25K, 10K, 5K, 2500, 1250
and 800. Finally obciously the tile size if you do not want the default.
