[mkgmap-dev] Commit: r1140: Added support for extended types.

Version 1140 was commited by markb on 2009-08-19 10:00:27 +0100 (Wed, 19 Aug 2009) Added support for extended types. These are sometimes called '3-byte types' but the upper 8 bits of the type is not encoded in the map objects (just the lower 16 bits) so any non-zero value for the upper byte has the same effect. Further work is needed to encode the extra bytes that specify stuff like depth and colour + all the detail associated with marine lights.
