#### camera(float angle, float height, float dist, vec2 resolution, out vec3 ro, out vec3 rd).
* angle is the camera's rotation around the origin in radians.
* height is the camera's height relative to the origin.
* dist is the distance the camera is placed from the origin.
* ro is the ray origin, which gets set as a result of
calling this function.
* rd is the ray direction, a unit vector which gets set as
a result of calling this function.

// Determine the ray origin/direction:

// Trace the scene:
