All,
With this patch, DungeonSiege is now starting to work and displays stuff. It
now gives me a lot of warnings about stuff not implemented (yeah :-) ).
There is still one *huge* problem : basically, it gives us completely bogus
lock rectangles at the first time it locks the front buffer to display the
mouse cursor... This means that for the game to work, you need an ugly hack
that 'sanitizes' the Lock rectangles (available on request :-) ).
Lionel
Changelog:
- added RGB 32 surface locking (seems to work fine without resorting to
Alpha hacks)
