Converts one color space to another. \n
* Images must be of the same size and data type. If color mode is the same nothing is done. \n
* CMYK can be converted to RGB only, and it is a very simple conversion. \n
* All colors can be converted to Binary, the non zero gray values are converted to 1. \n
* RGB to Map uses the median cut implementation from the free IJG JPEG software, copyright Thomas G. Lane. \n
* Alpha channel is considered and Transparency* attributes are converted to alpha channel. \n
* All other color space conversions assume sRGB and CIE definitions, see \ref color. \n
* Returns IM_ERR_NONE, IM_ERR_DATA or IM_ERR_COUNTER, see also \ref imErrorCodes. \n
* See also \ref imColorSpace, \ref imColorModeConfig and \ref colormodeutl.
