[b]Note:[/b] This method lerps through the shortest path between [code]from[/code] and [code]to[/code]. However, when these two angles are approximately [code]PI + k * TAU[/code] apart for any integer [code]k[/code], it's not obvious which way they lerp due to floating-point precision errors. For example, [code]lerp_angle(0, PI, weight)[/code] lerps counter-clockwise, while [code]lerp_angle(0, PI + 5 * TAU, weight)[/code] lerps clockwise.
