The following patch adds Metal.framework to the "link binary with libraries" section of each test program, with "status" set to "optional", which fixes link errors on all of the test programs. I'm not sure if this is a correct fix - the fact that this was necessary might indicate the static SDL2.a library has a hard dependency on Metal.framework (?) - but it gets the test programs working in Xcode again.
It also adds testyuv_cvt.c to the testoverlay2 target, fixing a link error.

Seems latest google angle library successfully built & tested under macOS'es.

We need to use GLES2 to implement true cross-platform code.
New functions get and set the YUV colorspace conversion mode:
SDL_SetYUVConversionMode()
SDL_GetYUVConversionMode()
SDL_GetYUVConversionModeForResolution()
SDL_ConvertPixels() converts between all supported RGB and YUV formats, with SSE acceleration for converting from planar YUV formats (YV12, NV12, etc) to common RGB/RGBA formats.
Added a new test program, testyuv, to verify correctness and speed of YUV conversion functionality.

Xcode 9 emits a warning to validate project settings. The changes it proposes are
1. [iOS] Update the iOS deployment target to 8.0 since Xcode does
not support anything older.
2. [macOS] Target 'Framework' - Automatically Select Archectures.
3. [iOS & macOS] Turns on a bunch more compile warnings, a *lot* more on iOS.
4. [iOS & macOS] Turn on "Missing Localizability".
I want to confirm if it is ok to accept these changes and submit updated project files.
Since Alex Szpakowski has just removed iOS 7 guard ifdef's, I'm guessing 1 isn't a problem.
2 is probably ok for anyone building themselves. I wonder if it may cause problems for building distribution binaries.
3 shouldn't be a problem either provided any newly emitted warnings are fixed.
4 I am unfamiliar with. The description says "This will turn on the static analyzer to check for "Missing Localizability", because this project is localized for multiple languages." I suppose this may cause new warnings.
This work was done by Jacob Lifshay and Mark Callow; I'm just merging it
into revision control.

Note that linking with AVFoundation is now required if you don't disable SDL_audio compilation on iOS and tvOS.

rename : src/audio/coreaudio/SDL_coreaudio.c => src/audio/coreaudio/SDL_coreaudio.m
I think this was important for SDL 1.2 because some targets needed
special device memory for DMA buffers or locked memory buffers for use in
hardware interrupts or something, but since it just defines to SDL_malloc
and SDL_free now, I took it out for clarity's sake.

Code signature can be added after build with the following command line:

SDL's Cocoa backend uses the CGDisplayMode API to get refresh rate information about a display mode, but CGDisplayModeGetRefreshRate will return 0 on most non-CRT monitors.
The only way I know of to get correct refresh rate information in OS X is via the CoreVideo DisplayLink API.
I have attached a patch which tries to use the CVDisplayLinkGetNominalOutputVideoRefreshPeriod function if CGDisplayModeGetRefreshRate fails, which fixes display mode refresh rate information on the monitors I tested.
The CVDisplayLink API requires linking with the CoreVideo framework, and the patch updates the various build files to do so.

The dynamic library (extracted from SDL2-2.0.3.dmg and put in /Library/Frameworks/) references the __Block_copy symbol in /usr/lib/libSystem.B.dylib, which cannot be found:
dlopen(/Library/Frameworks/SDL2.framework/SDL2, 6): Symbol not found: __Block_copy
Referenced from: /Library/Frameworks/SDL2.framework/SDL2
Expected in: /usr/lib/libSystem.B.dylib
From what I could gather __Block_copy seems to be related to the blocks extension to the C programming language introduced by Apple since OSX-10.6 (see: http://thirdcog.eu/pwcblocks/). If this is indeed the case, I don't think the SDL2-2.0.3.dmg on the website is at all compatible with OSX-10.5 countrary to what is announced.
