-speed maps to VP8ESETCPUUSED [-16,16].

While this establishes the framework for libvpx codec specific options I was wondering about name clashes with these. Is 'speed' too generic for this? doesn't it map to 'threads' ? -threads/threadcount is already used to populate gthreads. Could you please point me to the options or reply with an summary? I had the attached doxygen around, all N/A's take library defaults. Shorter inline text version (libvpx/AVCodecContext/option) below. The resulting configuration can be output at -loglevel debug.
