Texture rendering mostly works now. Even SDL_TEXTUREACCESS_STREAMING is supported now with a little overhead. Scaling of textures happens using XRender. :D

SDL_Textures should work with XRender now provided that the texture format and screen format match. This is only a temporary limitation.

X11_RenderFillRects and X11_RenderDrawRects use a server side mask pixmap of 1 bit depth now. All drawing on these pixmaps is done by server side functions such as XDrawRectangles and XFillRectangles.

X11_DrawRects now uses a very hacky way of drawing rectangles with XRender. This will be improved in some time.

Fix X11_FillRects to work with double buffering as well as triple buffering. This requires that the buffer pixmap be cleared after every render.

Fix the rendering color channels to be premultiplied with the alpha channel as thats what Xrender expects. Small fixes in X11_CreateTexture. Add some new functions in SDL_x11sym.h as well as support for Xrender.

Xrender uses 16 bit color per channel. Fixed the color handling in X11_RenderFillRects to match this. Xrender just works now for filling rectangles :D .

Modified configure.in to allow building with Xrender. Fixed all problems that prevented compilation.
Builds fine now :)

These include support for drawing a texture using the core protocol
while other textures are drawn using Xrender if Xrender does not support
the color format of the said texture or any other fault with Xrender.

Fixed the XRenderPictureAttributes value in X11_CreateRenderer with graphics_exposures = False.

Start work on Xrender specific additions to X11_TextureData and X11_CreateTexture.

Added some more attributes (specific to Xrender) to the X11 structs.
Added some code for querying the Xrender extension.

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.
