GeoTiff writer will fail for any custom EPSG code
-------------------------------------------------
Key: GEOT-3366
URL: http://jira.codehaus.org/browse/GEOT-3366
Project: GeoTools
Issue Type: Bug
Affects Versions: 2.7-M5
Reporter: Andrea Aime
Assignee: Simone Giannecchini
Fix For: 2.7-beta1
Trying to encode a raster whose projection is, for example, EPSG:900913, will
fail with the following stack trace:
{code}
java.lang.IllegalArgumentException: offset is not a TIFF USHORT

org.geotools.coverage.grid.io.imageio.geotiff.GeoTiffIIOMetadataEncoder.addGeoKeyEntry(GeoTiffIIOMetadataEncoder.java:298)

{code}
This is happening because the EPSG code returned is not a short. The code is
likely to be fixed by checking if the code is actually a short:
{code}
final int code = getEPSGCode(projectedCRS);
if (code != -1 && code <= Short.MAX_VALUE) {
metadata.addGeoShortParam(GeoTiffPCSCodes.ProjectedCSTypeGeoKey,
code);
return;
}
{code}
