Creates a unit [Vector2] rotated to the given [param angle] in radians. This is equivalent to doing [code]Vector2(cos(angle), sin(angle))[/code] or [code]Vector2.RIGHT.rotated(angle)[/code].

print(Vector2.from_angle(0)) # Prints (1.0, 0.0)
print(Vector2(1, 0).angle()) # Prints 0.0, which is the angle used above.
print(Vector2.from_angle(PI / 2)) # Prints (0.0, 1.0)

[b]Note:[/b] The length of the returned [Vector2] is [i]approximately[/i] [code]1.0[/code], but is is not guaranteed to be exactly [code]1.0[/code] due to floating-point precision issues. Call [method normalized] on the returned [Vector2] if you require a unit vector.
