Most users will have something in the radius or deadzone fields, so
don't bother filtering out 'extra' work. This also lets us clean up
the modifier implementation.
It was only used for really old joypads which we really don't want to
support. If users have these joypads, they should look into using
something at the OS level, as games shouldn't need to have this
transformation; it should be done by the OS and driver.
It substantially complicates the code and doesn't really provide any
functionality. According to the forums, the Android app is out of date
and has been broken for quite a while.
If we want to add this back, I'd write an app that speaks a more native
Wiimote protocol, and we can hook that up to the backend quite easily.
It could even be over our NetPlay protocol!
