Transparent ObjC<>C++ bridge
/*
Say you have a largeish C++ class. You want to use it from ObjC. ObjC++ is painful;
C++ is painful. .mm files are bad. How about if we could just treat that C++
object as an ObjC object whenever it exits C++ land?
Apple already solved this problem once with toll free bridging. The tricky part is
vtables -- with a vtable, isa isn't at offset 0 of the memory layout of the object.
The code below is a work in progress to work around this.

Don't use [NSDate timeIntervalFromReferenceDate] if you're working with deltas or timing or anything that isn't directly date related. Use absolute, monotonically increasing time instead. Using mach time is easy but slightly inconvenient; here's a very simple NSDate-like class you can use in your code.
#import <Foundation/Foundation.h>
@interface GFClock : NSObject
+ (instancetype)sharedClock;
// since device boot or something. Monotonically increasing, unaffected by date and time settings
- (NSTimeInterval)absoluteTime;
@end

A generic NSError presenter for iOS, like -[UIApp presentError::::]. Depends on some Lookback internals that should be easy to remove, but I need to sleep

Debug AVVideoCompositions using Apple's sample code, without having to find space *in your app* for its debug UI. I'm not sure what the correct way to license this is, but you're free to use it as you see fit as long as it conforms to Apple's original license :)
