WebKit style is brace on new line. Needs fixing all over this file.

Such a wall of code.

This should be int16_t.

> Tools/FontWithFeatures/FontWithFeatures/FontCreator.cpp:534
> +        append16(clampTo<int16_t>(unitsPerEm)); // Typographical descender

Might as well make is 1.

> Tools/FontWithFeatures/FontWithFeatures/FontCreator.cpp:537
> +        append16(clampTo<uint16_t>(unitsPerEm)); // Windows-specific descent

Ditto.

> Tools/FontWithFeatures/FontWithFeatures/FontCreator.cpp:656
> +        append16(clampTo<int16_t>(unitsPerEm)); // descent

Ditto.
