/*
 * $Log$
 * Revision 1.5  2006/11/08 22:47:24  tamas
 * Added typesafe ReadRaster/WriteRaster overloads
 *
 * Revision 1.4  2006/11/05 22:13:27  tamas
 * Adding the C# specific ReadRaster/WriteRaster
 *
 * Revision 1.3  2006/11/04 22:12:41  tamas
 * Added preliminary Raster R/W support
 *
 * Revision 1.2  2006/09/07 10:26:31  tamas
 * Added default exception support
 *
 * Revision 1.1  2005/09/02 16:19:23  kruland
 * Major reorganization to accomodate multiple language bindings.
 * Each language binding can define renames and supplemental code without
 * having to have a lot of conditionals in the main interface definition files.
