Started work on OS X 10.12 API stupids.

+
+// The OS X 10.12 SDK introduces a number of new names for
+// existing constants to align the naming conventions of
+// Objective-C and Swift (particularly in AppKit).
+// 
+// Unfortunately, in a baffling move, instead of using the existing
+// AvailabilityMacros.h method of marking things deprecated, they
+// rewrote the relevant constants in ways that make
+// source-compatible building much more annoying:
+// 
+// - The replacement names are now the only names in the enum
+// 	or define sets they used to be in.
+// - The old names are provided as static const variables, which
+// 	means any code that used the old names in a switch case now
+// 	spit out a compiler warning in strict C99 mode (TODO and in C++ mode?).
+// - The old names are marked with new deprecated-symbol
+// 	macros that are *not* compatible with the AvailabilityMacros.h
+// 	macros, meaning their deprecation warnings still come
+// 	through. (It should be noted that AvailabilityMacros.h was still
+// 	updated for 10.12 regardless, hence our #ifdef below.)
+// 
+// As far as I can gather, these facts are not documented *at all*, so
+// in the meantime, other open-source projects just use their own
+// #defines to maintain source compatibility, either by making the
+// new names available everywhere or the old ones un-deprecated.
+// We choose the latter.
+// TODO file a radar on the issue (after determining C++ compatibility) so this can be pinned down once and for all
+// TODO after that, link my stackoverflow question here too
+// TODO make sure this #ifdef does actually work on older systems
