the class PDColorSpace method create.

 * @param resources the current resources.
 * @param wasDefault if current color space was used by a default color space.
 * @return a new color space.
 * @throws MissingResourceException if the color space is missing in the resources dictionary
 * @throws IOException if the color space is unknown or cannot be created.
