# Float libvorbis: used only when float audio output is negotiated; decodes
# straight to float (vs Tremor's int16, which stays the default).  Vendored
# decode-only -- the encode machinery (psy/envelope/FFT) is replaced by no-op
# stubs in decode_stubs.c, since every reference to it sits behind an encode-
# only guard never taken on the decode path.  Symbol-namespaced to fv_* via
# fvorbis_rename.h (force-included below) so it links beside Tremor without
# colliding on the shared ov_*/vorbis_* names; the single vendored libogg is
# shared by both (its symbols are deliberately not renamed).
#
# deps/libvorbis/lib is kept OFF the global -I path: its generic header names
# (block.h, os.h, misc.h, window.h, info.h, ...) would shadow system headers
# of the same name, the same hazard documented above for deps/tremor.  The
# per-object CFLAGS add it locally to the vendored TUs only.  snd_vorbis_float.c
# needs just the public vorbis headers and namespaces the few ov_* entry points
# it calls in-source, so it only takes -I.../include.
