This is in prep for compiling with -std=c++14 and -Wno-c++17-extensions when building with clang. Chrome has encountered problems with third_party headers that are included both in Skia and other Chrome sources that produce different code based on whether preprocessor macros indicate a C++14 or C++17 compilation. In C++17 they are already inline implicitly. When compiling with C++14 we can get linker errors unless they're explicitly inlined or defined outside the class. With -Wno-c++17-extensions we can explicitly inline them in the C++14 build because the warning that would be generated about using a C++17 language extension is suppressed. We cannot do this in public headers because we support compiling with C++14 without suppressing the C++17 language extension warnings.
