[AD] Haptics

[Trent Gamblin <trent@xxxxxxxxxx>]

I'm writing a complete Lua binding for 5.1 so I'm going over the entire 
API. One thing that stands out is haptics. The API appears to be a thin 
layer over Linux kernel API. That means it's horrendous to actually use 
because it was never intended to be used directly. With all of the other 
APIs we sat down and thought of ways to make the interface useful, easy 
and simple but not with haptics. I'm proposing that we do a reboot of 
the haptics interface or at least consider some friendlier alternatives. 
When I look at it and try to actually implement a haptic effect without 
studying the code I want to punch my monitor because it's impossible, 
particularly the documentation for ALLEGRO_HAPTIC_EFFECT.
