SkColor.h uses #define liberally, and has many global symbols,
two things bookmaker hasn't seen in other includes.
Revised .h -> .bmh converter to work with SkColor.h as well
as updating how .bmh indices are built.
Generated SkColor_Reference.bmh for globals, and
SkColor4f_Reference.bmh for class.
Other than the existing comments, this doesn't update the
documentation or add new examples.
