I'm trying to use the rotation matrix to translate the accelerometer
values from the device coordinates to the world coordinates.  It's not
clear how to do this.  Theoretically, I should be able to do something
like this:

double[][] accelArray = {
                                        {xaccel},
                                        {yaccel},
                                        {zaccel}
                        };

Matrix accelDevice = new Matrix(accelArray);
                        Matrix accelWorld = rotationMatrix.times(accelDevice);

That code works for a third-party matrix library, but I can't figure
out how to do it with any of the SensorManager methods or the Android
Matrix classes.  Any help would be appreciated.
