The intent is for every color to be stored in a rgba instance The rgba class now stores the color in a 32 bit integer to save space This also removes the unused class rgb and moves everything else into a cpp file. Many functions also had weird template parameters. For example alpha_channel<unsigned short int> would give a 2 byte number with the alpha channel byte in both bytes. color_util::hex would return a hex string with alpha channel if unsigned short int was given and without if unsigned char was given. Even more curiously those parameters were passed to *_channel and the result nevertheless truncated to 8bits.
