I'd rather have them be different, since they're not really the same
thing. The idea is that we may have more than one family map to the same
type (e.g. currently both families 0 and 255 map to TYPE_NONE).

One last thing I just noticed, please don't rely on
ENABLE_EXPERIMENTAL_AMBISONICS actually being defined to zero when your
patch is disabled. Some people don't use the autotools build (e.g. they
use the plain Makefile or Visual Studio, or custom scripts), so your
patch would break their build. Instead, please rely on #ifdef's.

Cheers,
