Well, I do agree that that the new class is fine (and have no problem
with your proposal), but I'd like to understand why FOCUS_ABSOLUTE is
unsuitable. I'm actually thinking about writing very simple userspace
camera, without autofocus, where user would just select
"infinity"/"1m"/"50cm" ... and for that FOCUS_ABSOLUTE is equivalent
to VOICE_COIL_CURRENT...

What options would you like to see for movement mode?

Thanks,
