Fixes gdi32:dib / gdi32:bitmap tests and

CORE-16236 "SIMS graphics", which regressed by

Thanks to the patches author Doug Lyons.

It also fixed
CORE-16621 Kompozer 0.7.10 from rapps, exe does not show an icon, but does on 2k3sp2

fix picked from 0.4.15-dev-2850-g 847b037fe9

By taking the above, we also have to pick its addendum
[WIN32K] Fix 'use after free' in NtGdiStretchDIBitsInternal #4122 CORE-17861

0.4.15-dev-3420-g b538b9abb8
to avoid introducing another bug:
CORE-17861 MS Visual Studio 2010 Pro Fatal System Error 0x00000050
--------------
[WIN32K] Don't trust the BITMAPINFOHEADER size

This is not entirely correct yet, but less wrong than before and fixes

What is ReactOS?

ReactOS™ is an Open Source effort to develop a quality operating system that is compatible with applications and drivers written for the Microsoft® Windows™ NT family of operating systems (NT4, 2000, XP, 2003, Vista, Seven).

The ReactOS project, although currently focused on Windows Server 2003 compatibility, is always keeping an eye toward compatibility with Windows Vista and future Windows NT releases.

The code of ReactOS is licensed under GNU GPL 2.0+.

To build the system it is strongly advised to use the ReactOS Build Environment (RosBE). Up-to-date versions for Windows and for Unix/GNU-Linux are available from our download page at: http://www.reactos.org/wiki/Build_Environment.

Alternatively one can use Microsoft Visual C++ (MSVC) version 2010+. Building with MSVC is covered here: https://www.reactos.org/wiki/Building_with_MSVC.

Binaries

To build ReactOS you must run the configure script in the directory you want to have your build files. Choose configure.cmd or configure.sh depending on your system. Then run ninja <modulename> to build a module you want or just ninja to build all modules.

Bootable images

To build a bootable CD image run ninja bootcd from the build directory. This will create a CD image with a filename bootcd.iso.

See "Building ReactOS" for more details.

Installing

ReactOS currently can only be installed on a machine that has a FAT16 or FAT32 partition as the active (bootable) partition. The partition on which ReactOS is to be installed (which may or may not be the bootable partition) must also be formatted as FAT16 or FAT32. ReactOS Setup can format the partitions if needed.

To install ReactOS from the bootable CD distribution, extract the archive contents. Then burn the CD image, boot from it, and follow the instructions.

See "Installing ReactOS" Wiki page or INSTALL for more details.

Testing

If you discover a bug in ReactOS search on JIRA first - it might be reported already. If not report the bug providing logs and as many information as possible.

See "File Bugs" for a guide.

NOTE: The bug tracker is not for discussions. Please use #reactos Freenode IRC channel or our forum.

Contributing

We are always looking for developers! Check how to contribute if you are willing to participate.

More information

ReactOS is a Free and Open Source operating system based on the Windows architecture, providing support for existing applications and drivers, and an alternative to the current dominant consumer operating system.

It is not another wrapper built on Linux, like WINE. It does not attempt or plan to compete with WINE; in fact, the user-mode part of ReactOS is almost entirely WINE-based and our two teams have cooperated closely in the past.

ReactOS is also not "yet another OS". It does not attempt to be a third player like any other alternative OS out there. People are not meant to uninstall Linux and use ReactOS instead; ReactOS is a replacement for Windows users who want a Windows replacement that behaves just like Windows.

More information is available at: https://www.reactos.org.

Also see the media/doc subdirectory for some sparse notes.

Who is responsible

Active devs are listed as members of GitHub organization. See also the CREDITS file for others.

Code mirrors

The main development is done on GitHub. We have an alternative mirror in case GitHub is down.

There is also an obsolete SVN archive repository that is kept for historical purposes.
