Last change on this file since eaaa55b was 08253d9, checked in by Olly Betts <olly@…>, 18 years ago

Just set the pan and tilt directly as OpenGL rotations rather than messing
around setting up and then decoding a quaternion. This fixes some glitches
when tilting while looking east, and eliminates 2 source files and 2 headers!
