I reworked this a little. The 1.2 branch isn't really very elegant about this.

Renamed SDL_RenderPoint() and SDL_RenderLine() to SDL_RenderDrawPoint() and SDL_RenderDrawLine().
Added API for rectangle drawing (as opposed to filling)
Added placeholder API functions for circles and ellipses ... I'm not sure whether these will stay.
Optimized software line drawing quite a bit.
Added support for Wu's anti-aliased line drawing, currently disabled by default.

The thread ID is an unsigned long so it can hold pthread_t so people can do naughty things with it.
I'm going to be adding additional useful thread API functions, but this should prevent crashes in people's existing code on 64-bit architectures.

The SDL_MouseMotionEvent struct has a field named "tilt" (currently marked "for
future use"), for tablet stylus tilt information. However, one value is not
enough for this, as tilt is two-dimensional. Reserving only one field for
future use is no good when you're going to need two, so there should be two
fields, tilt_x and tilt_y.

Patch to use stdlib.h with Open Watcom
Open Watcom 1.8 has <stdlib.h> so instead of patch the single part when stdlib
features are used we use directly the include file as with GCC.

* Added display parameter to many internal functions so video modes can be set on displays that aren't the public current one.
* The fullscreen mode is associated with fullscreen windows - not displays, so different windows more naturally have a mode associated with them based on their width and height. It's no longer necessary to specify a fullscreen mode, a default one will be picked automatically for fullscreen windows.

If type is ::SDL_HAPTIC_CARTESIAN, direction is encoded by three positions
367 * (X axis, Y axis and Z axis (with 3 axes)). ::SDL_HAPTIC_CARTESIAN
uses
368 * the first three \c dir parameters. The cardinal directions would
be:
369 * - North: 0,-1, 0
370 * - East: -1, 0, 0
371 * - South: 0, 1, 0
372 * - West: 1, 0, 0
typedef struct SDL_HapticDirection
{
Uint8 type; /**< The type of encoding. */
Uint16 dir[3]; /**< The encoded direction. */
} SDL_HapticDirection;
An unsigned int can't store negative values and I don't see an alternate way to
encode them in the docs or source. The best I have been able to come up with is
using a negative magnitude for the effect but this will only get me 2 of the 4
quadrants in the plane for 2d effects. I looked at the win32 and linux
implementations and I believe is is safe to use signed ints in the direction
struct. I am unfamiliar with the darwin haptics API so I don't know if it is
safe.

This one is quite puzzling. I found a partial workaround, but I don't fully understand the reasons yet.
First, the console is complaining about not finding a nib for MainWindow.
I tried removing the entry for this in the info.plist, and the message went away, but it didn't really change anything.
Second, I stepped through this with the debugger and broke up some lines. It seems that the basic act of calling
view = [SDL_uikitopenglview alloc];
or even
view = [SDL_uikitview alloc]
will crash the program. The debugger messages plus the stack trace make me think it's not finding the SDL_uikitview classes for some reason. But I don't understand why this would be.
view = [UIView alloc] will not crash the program.
For kicks, I added a new definition of a class called SDL_object which subclasses NSObject in the same files as SDL_uikitopenglview and then call
view = [SDL_object alloc];
This does not crash the program.
So, then I modified SDL_object to subclass UIView. No crash.
Next, I made SDL_object subclass UIView<UITextFieldDelegate> . This crashes.
So it is the act of conforming to the UITextFieldDelegate protocol that is crashing things.
I don't understand why it would crash on alloc though. I'm guessing either a delegate needs to be set somewhere or one of the required methods needs to be implemented. But in the former case, I would not expect a crash, but a silent message to nil and something else doesn't work. And in the latter case, I would expect a compiler warning and an exception thrown instead of a crash.
Anyway, my temporary workaround is to change the interface declaration for SDL_uikitview to look like:
#if SDL_IPHONE_KEYBOARD
@interface SDL_uikitview : UIView<UITextFieldDelegate> {
#else
@interface SDL_uikitview : UIView {
#endif
And then disable the keyboard support in the SDL_config_iphoneos.h file.
/* enable iPhone keyboard support */
#define SDL_IPHONE_KEYBOARD 0

I'm building "fat" SDL 1.3 libraries for MacOSX, but now I am running into the
issue that audio does not work on PowerPC macintoshes if you build the library
on an Intel.
The problem is that configure hard-codes the byteorder, which is then stored in
SDL_config.h

I've been sitting on this too long. I need to push.
It's untested because of the unrelated crashing bug I've been experiencing.
Also have a fix for SIZEOF_VOIDP in the config for both iPhone and Mac.
