Release 961117 Sun Nov 17 15:01:45 1996 Alexandre Julliard <julliard@lrc.epfl.ch> * [graphics/bitblt.c] [graphics/x11drv/bitblt.c] Moved BitBlt operations to the new graphics driver interface. Implemented PatBlt32, BitBlt32 and StretchBlt32. * [memory/global.c] Unified MemManInfo() and GlobalMemoryStatus(). * [objects/text.c] Fixed ExtTextOut() to always use physical coords for clip rect. * [windows/dialog.c] Implemented DlgDirSelectEx() and Win32 version of DlgDirSelect*. * [windows/event.c] Avoid busy-looping in EVENT_WaitXEvent when no timer is pending (thanks to Thomas Koenig). * [windows/painting.c] Moved update region clipping for CS_PARENTDC windows to BeginPaint(). * [windows/scroll.c] Implemented Win32 version of ScrollWindow() and ScrollDC(). Tue Nov 12 09:52:17 1996 Marcus Meissner <msmeissn@cip.informatik.uni-erlangen.de> * [files/*.c] [win32/file.c] Some win32 filetime conversion functions added. Fixed behaviour with DOS drives pointing to UNIX / SetCurrentDirectory() may also get X:\xxx paths. Fixed FILE_Open when called from CreateFile(). Added GetFileSize(), MapViewOfFile(), SetFileTime(), GetFileTime(). * [misc/crtdll.c] [if1632/crtdll.spec] Added some new functions. * [if1632/user32.spec] Some thunks into win16 code added. * [win32/init.c] Added GetSystemInfo(), removed GetModuleFileName() stub. * [win32/code_page.c] [if1632/thunk.c] Added EnumSystemCodePages* (untested). * [objects/font.c] [if1632/thunk.c] Added EnumFontFamilies32*. Mon Nov 11 14:50:24 1996 Huw D. M. Davies <h.davies1@physics.oxford.ac.uk> * [controls/menu.c] [windows/mdi.c] Don't delete the MDI `windows' menu if it's already been deleted. * [misc/exec.c] Notepad always calls WinHelp(.., HELP_QUIT, ...) at termination and complains if it returns FALSE. * [windows/winpos.c] Get maximized MDI child's nonclient area redrawn after resize. Thu Nov 7 13:32:34 1996 Lee Jaekil <juria@seodu.co.kr> * [memory/global.c] Use /proc filesystem for GlobalMemoryStatus() on Linux. Mon Nov 4 18:30:00 1996 Alex Korobka <alex@trantor.pharm.sunysb.edu> * [windows/event.c] Added OffiX-style file drop handling. File paths must be DOS-mappable by Wine (via wine.conf). * [controls/combo.c] Added WM_GETTEXT handler. * [objects/palette.c] Added ResizePalette() (untested). * [objects/cursoricon.c] Implemented icon to cursor conversion. * [objects/color.c] Fixed crash on startup when no colorcells are writeable. Mon Nov 4 00:49:41 1996 Ulrich Schmid <uschmid@mail.hh.provi.de> * [rc/winerc.c] Added support for win32 output. * [library/libres.c] [include/libres.h] [loader/resource.c] Renamed LIBRES_FindResource to LIBRES_FindResource16. Added LIBRES_FindResource32. Sun Nov 3 21:21:45 1996 Robert Pouliot <krynos@clic.net> * [loader/builtin.c] [if1632/Makefile.in] [if1632/wing.spec] Added the spec file for WinG, it's only stub for now, but it should be easy to do by someone with Windows programming knowledge. See: ftp.microsoft.com/SoftLib/MSLFILES/wing10.exe. * [if1632/crtdll.spec] Added some string and memory functions to make sfxed95.exe (of Warcraft 2) almost work.
