Fixed bug #899

Re-enable mouseLocation workaround on 10.4, 10.5
OS X systems before 10.6 have a bug with [NSEvent mouseLocation] if the screen
resolution changes. SDL_QuartzVideo.m contains a workaround for this bug, but
it was placed inside an #ifdef in revision 4762. The comment reads, "I'm
gambling they fixed this by 10.4."
After seeing this bug on several Tiger and Leopard systems (both PPC and
Intel), I can confirm that it's not fixed until 10.6. The workaround doesn't
compile for x86_64/10.6, so I can understand why it was segregated, but it
needs to remain in place for the i386 and ppc versions. The workaround causes
no problems under 10.6, even though it's not necessary there.
Patch is attached with one method of keeping the workaround active on the
systems that need it.

* Porting To A New Platform The first thing you have to do when porting to a new platform, is look at include/SDL_platform.h and create an entry there for your operating system. The standard format is __PLATFORM__, where PLATFORM is the name of the OS. Ideally SDL_platform.h will be able to auto-detect the system it's building on based on C preprocessor symbols. There are two basic ways of building SDL at the moment: 1. The "UNIX" way: ./configure; make; make install If you have a GNUish system, then you might try this. Edit configure.in, take a look at the large section labelled: "Set up the configuration based on the target platform!" Add a section for your platform, and then re-run autogen.sh and build! 2. Using an IDE: If you're using an IDE or other non-configure build system, you'll probably want to create a custom SDL_config.h for your platform. Edit SDL_config.h, add a section for your platform, and create a custom SDL_config_{platform}.h, based on SDL_config.h.minimal and SDL_config.h.in Add the top level include directory to the header search path, and then add the following sources to the project: src/*.c src/audio/*.c src/cdrom/*.c src/cpuinfo/*.c src/events/*.c src/file/*.c src/joystick/*.c src/stdlib/*.c src/thread/*.c src/timer/*.c src/video/*.c src/audio/disk/*.c src/video/dummy/*.c src/joystick/dummy/*.c src/cdrom/dummy/*.c src/thread/generic/*.c src/timer/dummy/*.c src/loadso/dummy/*.c Once you have a working library without any drivers, you can go back to each of the major subsystems and start implementing drivers for your platform. If you have any questions, don't hesitate to ask on the SDL mailing list: http://www.libsdl.org/mailing-list.php Enjoy! Sam Lantinga (slouken@libsdl.org)
