[Pixman] pixman on iOS

I'll bring up an old topic as the issue came up again. I have been using
an old version of Pixman (0.24 I believe) with manual assembly
optimizations that someone posted here. It's been a couple of years
since it was posted. That version compiles on armv7 and is fairly fast.

As of June Apple requires apps to support both armv7 and arm64. I was
able to compile current pixman for both architectures without Neon (or
any other) optimizations. It appears that Neon optimizations for Pixman
are still not working on iOS. Without these optimizations rendering is
painfully slow.

- Is there an optimized version of Pixman for arm64/iOS (or, better yet,
for iOS in general)?
- What do folks at GStreamer use on iOS? Is their Pixman also unoptimized?

Thanks all!
