wine/include/gdi.h
Alexandre Julliard 60ce85c965 Release 980201 
Sun Feb  1 13:24:54 1998  Alexandre Julliard  <julliard@lrc.epfl.ch>

	* [files/drive.c]
	Added Device= parameter to drive configuration.

	* [if1632/relay.c]
	Throw() and Catch() now use the correct CATCHBUF layout (untested).

	* [tools/build.c] [include/stackframe.h] [loader/task.c]
	Moved 16-bit stack pointer into thread database.
	Save current %fs while running 16-bit code.

Fri Jan 30 09:25:49 1998  Martin Boehme  <boehme@informatik.mu-luebeck.de>

	* [graphics/mapping.c]
	Made DPtoLP32 and LPtoDP32 respect world transforms.

	* [graphics/path.c] [graphics/painting.c] [if1632/gdi.spec]
	  [include/path.h]
	More path support.

	* [include/gdi.h] [include/windows.h] [objects/dc.c]
	  [relay/gdi32.spec]
	Support for Get/SetArcDirection and Get/SetWorldTransform

	* [windows/hook.c]
	Fixed a bug in HOOK_Map16To32Common.

Thu Jan 29 23:43:18 1998  Douglas Ridgway <ridgway@taiga.gmcl.com>

	* [graphics/metafiledrv/init.c] [objects/metafile.c]
	Documentation for metafile related API calls. Fixed a bug to avoid
	documenting it.

	* [include/windows.h]
	Declaration for LoadImage.

Thu Jan 29 21:44:45 1998  Huw D M Davies <h.davies1@physics.oxford.ac.uk>

	* [graphics/win16drv/*]
	Changes to printing code to enable use of printer fonts with the
	win3.1 postscript driver. Remember to add printer=on to [wine]
	section of wine.conf . You will also need to disable truetype
	fonts from control panel. Winword 6.0 and Write seem to be happy
	with this...

	* [include/bitmap.h]
	Fix Widthbytes for 15bpp displays.

Tue Jan 27 20:54:08 1998  Kristian Nielsen <kristian.nielsen@risoe.dk>

	Implemented thread-safe X11 wrappers.

Tue Jan 27 13:54:09 1998  Constantine Sapuntzakis  <csapuntz@tma-1.lcs.mit.edu>

	* [windows/queue.c]
	Forgot to convert thdb to thread_id.

	* [misc/registry.c]
	Sped up Windows 95 registry reading. Changed code to traverse
	registry as a tree rather than read in all possible keys
	(including dead ones). 

Tue Jan 27 12:46:09 1998  Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de>

	* [loader/pe_image.c][Makefile.in][scheduler/thread.c]
	  [libtest/hello5.c]
	Don't exit() on failed to load referenced dlls.
	Fixed static tls allocation for multiple threads.
	WINELIB should now be able to load PE dlls. A sample
	winelib program, that dynamically loads a internal dll
	is included.

	* [graphics/ddraw.c][include/ddraw.h][include/d3d.h]
	Cleaned up and enhanced further. Added several DirectX5
	interface definitions and DirectSurface3 implementation.
	Stubs for D3D (NOT coming soon, just there so it fails safely).

	* [multimedia/dsound.c][include/dsound.h]
	Actually works now for a lot of cases. Some DirectX5 stuff
	added. Still lacking several features.

	* [windows/dinput.c][include/dinput.h]
	Started implementing DirectInput. Doesn't work yet, don't 
	know why.

	* [if1632/thunk.c][misc/callbacks.c]
	  [win32/kernel.c][include/callbacks.h]
	Added WOWCallback16Ex, WOWHandle32.

	* [misc/cpu.c]
	Fixed GetSystemInfo, IsProcessorFeaturePresent.

	* [configure.in]
	Fixed check for union semun on FreeBSD systems.

Sun Jan 18 23:05:04 1998  Karl Backström <karl_b@geocities.com>

	* [misc/ole2nls.c] [programs/progman/Sw.rc] [programs/winhelp/Sw.rc]
	  [resources/sysres_Sw.rc]
	Added/updated Swedish language support.

Sun Jan 18 18:49:01 1998  Alex Korobka <alex@trantor.pharm.sunysb.edu>

	* [misc/winsock.c] [misc/winsock_dns.c] [windows/event.c]
	  [windows/win.c] [windows/dce.c] [windows/winpos.c]
	Bug fixes.

Sun Jan 18 12:45:23 1997  Andreas Mohr <100.30936@germany.net>
