Alexandre Julliard 18506558a7 Release 950122
Sun Jan 22 18:55:33 1995  Alexandre Julliard  (julliard@lamisun.epfl.ch)

	* [loader/resource.c] [objects/dib.c]
	Fixed icon loading and drawing, now that BitBlt() works correctly.
	
	* [objects/clipping.c] [objects/region.c]
	Implemented elliptic regions with a set of rectangle. This greatly
	simplifies the region code and should boost clipping performance.

	* [objects/color.c]
	Fixed bug that caused seg-fault on 24bpp displays.

	* [objects/bitblt.c]
	Fixed bug when shrinking a bitmap to more than half its size.

	* [windows/graphics.c]
	Fixed bugs in PaintRgn() and Polyline().

	* [windows/nonclient.c] [windows/painting.c] [windows/winpos.c]
	Fixed some problems with window background painting.

       * [tools/build.c]
       * [tools/newbuild.c]
       * [Imakefile]
       * [include/wine.h]
       * [loader/call.S]
       * [loader/selector.c]
       * [include/segmem.h]
       * [misc/main.c]
       Changed selector code and 16/32 bit xfer code so that wine
       no longer has to be loaded low in memory.  Changed wine
       to work with ELF binary formats under Linux.

	* [debugger/db_disasm.c]
	New instruction disassembler - borrowed from Mach kernel.  Has a
	BSD style of license as opposed to the gdb code we were previously
	using which was under the GPL.

Mon Jan  9 18:27:11 1995  Alexandre Julliard  (julliard@lamisun.epfl.ch)

	* [Imakefile]
	Compiling with -Wall flag.

	* [*/*]
	Fixes to minimize the number of compilation warnings.

	* [objects/bitblt.c]
	Fixed BitBlt() and used the same code to rewrite PatBlt() and
	StretchBlt(). The three *Blt() functions should now be correct in
	every case (famous last words).

	* [objects/brush.c] [objects/dither.c]
	Merged the two files into brush.c

	* [objects/dc.c]
	Fixed bug when the Windows programs forget to re-select the
	original bitmap in a memory DC.

	* [objects/font.c]
	Tty to use 'fixed' font when the system font can't be found.

	* [windows/dialog.c]
	Tentative fix to make dialogs look better when using fixed-width
	fonts.

	* [windows/graphics.c]
	Partially implemented the PS_INSIDEFRAME pen style.

	* [windows/nonclient.c]
	Fix for windows that have the WS_EX_DLGMODALFRAME style bit
	without the WS_DLGFRAME style.
