[Bf-committers] Sensors API for GE on Android

[Campbell Barton]

Hi, adding a python api to begin with seems reasonable (keep in mind
we may wan't C/api for other parts of blender to access but this
shouldn't be a problem)

Check on...
http://www.blender.org/documentation/blender_python_api_2_63_release/bge.logic.html#bge.logic.mouse
http://www.blender.org/documentation/blender_python_api_2_63_release/bge.events.html

There could be...

bge.logic.gyroscope
bge.logic.gyroscope.is_connected
bge.logic.gyroscope.activate()
bge.logic.gyroscope.deactivate()
quat = bge.logic.gyroscope.angular_velocity  # rotation as a quaternion
data = bge.logic.gyroscope.data  # raw data from gyro -- if this is
useful in some cases it have besides quaternion access.
