The engine name was upper-case 'DGDS', but make it lower-case 'dgds' for
consistency with other engines.
This requires ini file entries to be updated by hand or re-added, but the
engine is not yet in testing so not many users will be affected.
It doesn't even start at this point, as the engine is quite
newer, and this game some drastic changes from previous ones
(e.g. the scene version is 2.xxx now, and there doesn't seem
to be any inventory)
This is the initial import of the sources from vcosta's implementation.
Work has progressed on that base, so that it forms into an actual engine.
There has been heavy refactoring into classes, but there's still loads of
work to be done.
The status is almost the same the original vcosta's engine: it's possible
to play the intro Rise of the Dragon, and parts of the intro of Heart of
China and Willy Beamish. The DOS VQT images are still not decoded, so only
the Mac versions work for now - or the DOS versions with the Mac images
as patches
