std::tuple< double, double > Mouse::get_yaw_pitch_deltas	(	double	mouse_position_x,
		double	mouse_position_y,
		double	senstivity_override = -1 )

Get delta angles based on mouse.

Take in absolute mouse positions and turn them into delta angles wrt yaw and pitch

Note: In radians tau = 2 * pi ~= 6.28 represents a full rotation, and on average we can assume that a a player usually wants to rotate their view angle by theta := tau/4 ~= 1.57, also note that delta mouse positions are coming in at (probably) a rate of at least 60Hz, which means that if a player wants to rotate their view by theta in one second they must at least be producing deltas of size theta/60 = 0.0261.

On average it seems that most mice produce deltas of size TODO, which are much greater than this value, and a general rule of thumb is that to produce good delta angles, we should scale down our delta by 1000x

Parameters

mouse_position_x	the current mouse x position
mouse_position_y	the current mouse y position

Returns: a tuple t such that t1 is the change in yaw angle, and t2 is the change in pitch angle
