Alexandre Julliard 54c2711ff6 Release 980329
Sun Mar 29 15:18:57 1998  Uwe Bonnes <elektron.ikp.physik.tu-darmstadt.de>

	* [msdos/int21.c]
	More verbose Trace messages

Sun Mar 29 15:03:30 1998  Alexandre Julliard  <julliard@lrc.epfl.ch>

	* [loader/ne_image.c]
	Terminate relocation chains on 0 offset.

Sun Mar 29 02:35:45 1998  James Juran  <jrj120@psu.edu>

	* [windows/caret.c] [windows/class.c] [windows/clipboard.c]
	Fixed more USER32 ordinal numbers in function documentation.

Sat Mar 28 22:40:23 1997  Andreas Mohr <100.30936@germany.net>

	* [controls/desktop.c]
	Return 1 for WM_NCCREATE in DesktopWndProc.

	* [controls/menu.c]
	Fixed crash when destroying a top popup win that was only created
	but not shown.

	* [ole/typelib.c] [if1632/typelib.spec]
	Implemented OABuildVersion.

	* [windows/win.c]
	Finally fixed ugly bug in GetParent32 that affected window placement:
	Didn't return 0 for windows that have neither WS_POPUP nor
	WS_CHILD set. Now it acts exactly like Windows (at least I hope so ;)

Sat Mar 28 02:26:43 1998  Dimitrie O. Paun  <dimi@mail.cs.toronto.edu>

	* [DEVELOPERS-HINTS] [documentation/debug-msgs]
	Updated documentation on debug messages

	* [include/button.h] [controls/button.c] [include/windows.h]
	[include/combo.h] [controls/combo.c] [controls/commctrl.c]
	[controls/icontitle.c] [controls/listbox.c]	[controls/menu.c]
	[controls/scroll.c] [controls/widgets.c] 
	Changed some 16-bit code to 32-bit code. I am positive this will
	not break anything.

	* [controls/uitools.c] 
	Renamed the prefix of some functions from UITOOLS_ to UITOOLS95_
	to reflect the fact that they implement Win95 look. Maybe we will
	have a UITOOLS31_ in the future. Anyhow, the change is completely
	internal to this file.

	* [*/*.c]
	Changed a lot of [f]printf into appropriate debug messages.

Fri Mar 27 19:56:12 1998  Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>
	* [documentation/status/]
	Added directdraw and directsound status.

	* [if1632/thunk.c][ole/*.c][win32/kernel32.c]
	Added some documentation.
	Moved FUNC004 to thunk.c since it seems to be a 16->32 thunk
	(calling conventions and the like still unknown).

Fri Mar 27 09:59:32 1998  Morten Eriksen  <mortene@pvv.org>

	* [loader/resource.c][windows/keyboard.c]
	Implemented CopyAcceleratorTable() and CreateAcceleratorTable().
	
	* [include/compobj.h][ole/compobj.c][relay32/ole32.spec]
	Added implementation of StringFromGUID2(). 

Tue Mar 26 23:12:05 1998  Eric Kohl <ekohl@abo.rhein-zeitung.de>

	* [misc/imagelist.c][relay32/comctl32.spec]
	Implemented new debugging interface.
	Added missing functions (some are empty stubs).

	* [objects/oembitmaps.c][include/windows.h]
	  [include/bitmaps/*]
	Added missing restore bitmaps for Win95 look.
	Added missing Win95 cursors.

	Fix compilation, Aldus placeable metafile loading.

	* [graphics/metafiledrv/init.c] [relay32/gdi32.spec] 
	  [objects/metafile.c]
	Implemented various 32 bit versions of regular metafile API.

	* [objects/enhmetafile.c]
	Implemented rendering of a couple of dozen records.

Tue Mar 24 20:06:39 1998  Matthew Becker <mbecker@glasscity.net>

	the MIDI devices, for future use.

Thu Mar 19 00:59:29 1998  Jim Peterson <jspeter@nospam.birch.ee.vt.edu>

	* [windows/win.c]
	Eliminated inaccurate setting of cs->hMenu in
	WIN_CreateWindowEx, along with superfluous SetMenu32 call.

Mon Mar 16 17:40:53 1998  Petter Reinholdtsen <pere@td.org.uit.no>

This file contains information on the current implementation of the DirectSound
API.
The DirectSound API can be found in the Win32 DLL dsound.dll and in the
IDirectSound* interfaces. It is implemented in multimedia/dsound.c.
The current implementation uses the Linux/FreeBSD OpenSoundSystem. Some
applications already work. There is only the basic part of the interfaces
implemented, but it is the stuff used by 90% of the applications.
It also uses multithreading, so it will only work on systems with working
CreateThread.
Tested with SoundBlaster(16) clone and Gravis UltraSound Classic.
TODO:
- Add support for other audiosystems.
+ Sun Audio. (Solaris and probably the *BSDs except FreeBSD.)
+ remote audio support (No clue as to what systems there are.
Use some audio xextensions?)
- Add support for mixing of different frequency and panning.
- Fix all the multithread pending race conditions and the like.
- Share filedescriptors and other stuff with mciwave/waveoutdevice code.
Gamestatus:
- Wing Commander 4/W95:
The intromovie plays without problems. Nearly lipsynchron.
- DiscWorld 2
The sound works, but noticeable chunks are left out (from the sound
and the animation). Don't know why yet.
- Diablo:
Sound works, but slows down the movieplayer. In the (hacked version)
game the sound is positively weird.
- Monkey Island 3:
The background sound of the startscreen works.
- WingCommander Prophecy Demo:
Sound works for the intromovie.
