/**
* @file camera.c
* Implements the camera system, including C-button input, camera modes, camera triggers, and cutscenes.
*
* When working with the camera, you should be familiar with sm64's coordinate system.
* Relative to the camera, the coordinate system follows the right hand rule:
* +X points right.
* +Y points up.
* +Z points out of the screen.
*
* You should also be familiar with Euler angles: 'pitch', 'yaw', and 'roll'.
* pitch: rotation about the X-axis, measured from +Y.
* Unlike yaw and roll, pitch is bounded in +-0x4000 (90 degrees).
* Pitch is 0 when the camera points parallel to the xz-plane (+Y points straight up).
*
* yaw: rotation about the Y-axis, measured from (absolute) +Z.
* Positive yaw rotates clockwise, towards +X.
*
* roll: rotation about the Z-axis, measured from the camera's right direction.
* Unfortunately, it's weird: For some reason, roll is flipped. Positive roll makes the camera
* rotate counterclockwise, which means the WORLD rotates clockwise. Luckily roll is rarely
* used.
*
* Remember the right hand rule: make a thumbs-up with your right hand, stick your thumb in the
* +direction (except for roll), and the angle follows the rotation of your curled fingers.
*
* Illustrations:
* Following the right hand rule, each hidden axis's positive direction points out of the screen.
*
* YZ-Plane (pitch) XZ-Plane (yaw) XY-Plane (roll -- Note flipped)
* +Y -Z +Y
* ^ ^ (into the ^
* --|-- | screen) |<-
* +pitch / | \ -pitch | | \ -roll
* v | v | | |
* +Z <------O------> -Z -X <------O------> +X -X <------O------> +X
* | ^ | ^ | |
* | \ | / | / +roll
* | -yaw --|-- +yaw |<-
