Fixed bug #849 some more:

Fix to the cursor not being responsive when the app doesn't have
SDL_APPINPUTFOCUS
The problems with the directx driver are similar to the ones I introduced in
the windib driver with r4478. Basically if the application did not have focus,
the mouse position is not updated. It's not really that the mouse cursor was
invisible, it's that it is stuck underneath another window where you can't see
it. This behaviour predates my r4478 changes and is the reason I unwittingly
broke the windib driver as I had been replicating the way the directx driver
deals with focus. Prior to r4478 the directx driver could not be used in
windowed mode, so the broken focusing would not have actually been observable.
Anyway, the attached patch makes the directx driver behaves like the windib
driver in terms of focus.
Time for 1.2.15? ;)
I've added an additional change of moving the calls to WIN_GrabInput that are
made on WM_ACTIVATE messages so that they only occur when the state is
SDL_APPINPUTFOCUS. When a fullscreen application is minimised using alt-tab, it
still receives WM_ACTIVATE messages when other applications are selected. If
WIN_GrabInput is called when the SDL application doesn't have input focus, bad
things happen; it shouldn't be being called at all.
I've also added a line to make sure that SDL_APPMOUSEFOCUS state is dropped
when the application is minimised following an alt-tab.

Simple DirectMedia Layer (SDL) Version 1.2 --- http://www.libsdl.org/ This is the Simple DirectMedia Layer, a general API that provides low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D framebuffer across multiple platforms. The current version supports Linux, Windows CE/95/98/ME/XP/Vista, BeOS, MacOS Classic, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. The code contains support for Dreamcast, Atari, AIX, OSF/Tru64, RISC OS, SymbianOS, Nintendo DS, and OS/2, but these are not officially supported. SDL is written in C, but works with C++ natively, and has bindings to several other languages, including Ada, C#, Eiffel, Erlang, Euphoria, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP, Pike, Pliant, Python, Ruby, and Smalltalk. This library is distributed under GNU LGPL version 2, which can be found in the file "COPYING". This license allows you to use SDL freely in commercial programs as long as you link with the dynamic library. The best way to learn how to use SDL is to check out the header files in the "include" subdirectory and the programs in the "test" subdirectory. The header files and test programs are well commented and always up to date. More documentation is available in HTML format in "docs/index.html", and a documentation wiki is available online at: http://www.libsdl.org/cgi/docwiki.cgi The test programs in the "test" subdirectory are in the public domain. Frequently asked questions are answered online: http://www.libsdl.org/faq.php If you need help with the library, or just want to discuss SDL related issues, you can join the developers mailing list: http://www.libsdl.org/mailing-list.php Enjoy!
