204 Return the generic RGB color space. This is a 'get' function and the caller should
205 not release the returned value unless the caller retains it first. Usually callers
206 of this routine will immediately use the returned colorspace with CoreGraphics
207 so they typically do not need to retain it themselves.
209 This function creates the generic RGB color space once and hangs onto it so it can
210 return it whenever this function is called.
