* Now we're ready to draw some 3D objects

* All the magic happens here. The rotation matrix mR reported by
* SensorManager.getRotationMatrix() is a 4x4 row-major matrix.
* We need to use its inverse for rendering. The inverse is
* simply calculated by taking the matrix' transpose. However, since
* glMultMatrixf() expects a column-major matrix, we can use mR
* directly!
