Added automated test to Xcode project plus needed changes to SDL_RWFromFile to be OS X bundle aware. The Mac OS X project has a new target called testsdl which builds the automated test. I looked at using Xcode's native unit test support, but the impedance mismatch between the existing automated test structure and Apple's was more than I could handle. As such, the testsdl application is a full blown proper OS X application, which means it is a self-contained .app bundle. This immediately revealed some problems from the automated test. The largest problem was the assumption about the current working directory and where to find resources. (I suspect Windows may have a similar problem depending on circumstance.) To open resources, the test was looking in directories relative to the SDL source directory, but this will not work well with self-contained .app bundles and Xcode which can place its built applications almost anywhere. And for real-world situations, this is pretty useless anyway. So I modified SDL_RWFromFile to do special things on OS X. First, it will look for a file in the .app bundle. If not found, it will fallback and just call fopen as it used to do. I also had to modify the automated test itself because it had a contrieved test which called fopen directly to do read from an existing FILE pointer. In addition, there was a write test. Since a .app bundle is likely going to be read-only, I added a special case for OS X to write to NSTemporaryDirectory. I expect these changes should work for both Mac and iPhone OS (which includes iPad). I will update the iPhone Xcode project next. Finally, FYI, the X11 automated test seems to be failing. Below is my output.

   SDL Automated Testing Framework User Documentation
   by Edgar Simo Serra



   Abstract

   The SDL Automated Testing Framework, hereby after called SDL_AT, is a meant
to test the SDL code for regressions and other possible failures. It can also
be used to display what your SDL set up supports.



   Basics

   The main way to use the framework is to compile it and run it, that can be
done with the following command:

  $> make test
  
  It should then display something like:

  Platform : All tests successful (2)
  SDL_RWops : All tests successful (5)
  SDL_Surface : All tests successful (6)
  Rendering with x11 driver : All tests successful (4)

  Indicating that all tests were successful. If however a test fails output it
will report the failure to stderr indicating where and why it happened. This
output can then be sent to the developers so they can attempt to fix the
problem.



   Advanced

   By passing the "-h" or "--help" parameter to testsdl you can get an overview
of all the possible options you can set to furthur tweak the testing. A sample
of the options would be the following:

   Usage: ./testsdl [OPTIONS]
   Options are:
      -m, --manual    enables tests that require user interaction
      --noplatform    do not run the platform tests
      --norwops       do not run the rwops tests
      --nosurface     do not run the surface tests
      --norender      do not run the render tests
      -v, --verbose   increases verbosity level by 1 for each -v
      -q, --quiet     only displays errors
      -h, --help      display this message and exit
