Replaced the model of treating a window's shape as a render target with treating a window's shape as a surface passed into an SDL_SetWindowShape() function.  I'll send this off to Andreas and Sam and start coding.

Stubbed out the new get/set parameter functions, added the start of the enum, union, and struct for those parameters themselves, and added doxygen comments throughout the SDL_shape.h header.

Moved the SDL_Eyes test program for shaped windows into the Hg repository and got it building and linking as a test.

Added the standard headers and footers that make SDL_shape.h and SDL_shape.c integrate properly into the build.

Changed API for shaped windows to make it much, much simpler.  A shaped window's shape mask is now accessed as a render target, which means we can get at it with blit and draw functions, as well as (most likely) OpenGL.

I'm actually going to have to alter this proposed API a fair bit, but it's coming along.  I want to keep it as orthogonal to the rest of SDL as possible.

The refactored tests were written in recognition that Mac and iPhone current working directories are usually not going to work. Resource directories are in bundles and write directories are restricted to certain areas. In theory, other platforms may have this problem too, hence the refactoring.

Also updated the Xcode iPhone project to use 3.2 as the Base SDK, but 3.1 as the Deployment SDK (for iPhone/iPad compatibility.)

--HG--
rename : test/automated/rwops/Test_rwopsbundlesupport.h => test/automated/rwops/TestSupportRWops.h
rename : test/automated/rwops/Test_rwopsbundlesupport.m => test/automated/rwops/TestSupportRWops_Cocoa.m

Looks like there is a problem with the source code base. UIScreenMode and possibly a few other 3.2 only APIs have crept in. 3.2 is only available for iPad, and not iPhone/iPod Touch.

I haven't updated yet to the 3.2 SDK so SDL no longer builds for me so I can't yet verify if the new target completely works.

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.

Fixes most issues and limitations, I think.

(a similar test is output by Xcode for the iPhone View Application template).

The iPad (and iPhoneOS 3.2) introduce both a larger screen and the ability to
 enumerate and configure external displays. This hooks up SDL's multi-display
 API to this new functionality, and removes the hardcoded iPhone resolution.

Please add a #serial line as below to sdl.m4 and increase the serial number
with each revision of this file. This allows using aclocal --install, thereby
enabling automatic updating of sdl.m4 in SDL-based packages that distribute it.

# serial 1

The complete documentation and rationale for #serial can be found in the
Automake documentation:
