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. Thu Jan 12 12:20:25 PST 1995 Ross Biro (biro@yggdrasil.com) * [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. Sat Sep 17 11:08:49 1994 Eric Youngdale (eric@esp22) * [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.
