pivot_point

///@func				pivot_point()
///@desc				Given an 'origin' point, pivot another point around it.
///						Takes in origin point coordinates, pivoting point distance (relative = true) or absolute coordinates (relative = false)
///						Returns an [x,y] array with the pivoted point coordinates
///
///@param origin_x		Origin X
///@param origin_y		Origin Y
///@param point_x		Point X distance or X coordinate
///@param point_y		Point Y distance or Y coordinate
///@param relative		[Boolean] Point is passed as distance from origin (true) or absolute coordinates (false)
///@param pivot_angle	The angle at which the point is to be pivoted
