[geotk] applet to display raster

[Martin Desruisseaux]

Maybe the image does not contains georeferencing information. It could be the 
case if the Java TIFF image reader has been used instead of the GeoTIFF reader. 
After registering the JAI reader explicitely, we also need to register the 
GeoTIFF reader explicitely:

IIORegistry.getDefaultInstance().registerServiceProvider(new
GeoTIFFImageReader.TIFF(), ImageReaderSpi.class);


We need to do that because the automatic registration of GeoTiffImageReader 
failed since it didn't found the Java TIFF reader at that time.
