/** @brief Rotates a 2D array in multiples of 90 degrees.
The function rotate rotates the array in one of three different ways:
* Rotate by 90 degrees clockwise (rotateCode = ROTATE_90).
* Rotate by 180 degrees clockwise (rotateCode = ROTATE_180).
* Rotate by 270 degrees clockwise (rotateCode = ROTATE_270).
@param src input array.
@param dst output array of the same type as src. The size is the same with ROTATE_180,
and the rows and cols are switched for ROTATE_90 and ROTATE_270.
@param rotateCode an enum to specify how to rotate the array; see the enum RotateFlags
