added getAbsoluteTilt/Roll to get camera inclination from accelerometers

[arturoc]

useful to correct the 3d scene based on the camera inclination.

not very sure about the naming, was going to call it just getRoll/getTilt but it can be confusing with the getCameraTilt to get the inclination of the servos.

perhaps getAccelRoll/Tilt?

do you find that this is pretty accurate?
I think getAccel roll / tilt might be a little more descriptive.

[arturoc]

yes, it seems to be pretty accurate, i actually need it for an
installation so i expect it'll work :)

that's awesome! i would say don't use the word 'tilt', because it's ambiguous. use the usual 'roll, pitch & yaw' nomenclature.

i think also maybe more helpful than having those two values would be to construct a 3x3 or 4x4 rotation matrix that can be used to transform points.

[arturoc]

yes i guess pitch/roll makes more sense and avoids ambiguities with the
servos tilt.

so getPitch/getRoll?
