Zephaniah E. Hull cffc51e04a evdevAbsRec: Remove the scale bool, rename scale_x and scale_y to scale[2].
evdevAxesRec: Make btnMap an int array instead of a Card8 array.
Make abs support and non-core stuff actually work.
Relative emulation for abs mode is still a bit broken, but that's far less
    critical.
How many buttons we've registered is configuration information, not an
    error message.
