* Removed unused MakeBlendColor().
* At least 15 bit mode is broken, and should probably be removed. * Cleanup - do we really need this class? git-svn-id: file:///srv/svn/repos/haiku/haiku/trunk@16247 a95241bf-73f2-0310-859d-f6bbb57e9c96

\brief A color class to encapsulate color space ugliness in the app_server
|

|

RGBColors can be used to perform tasks much more difficult using rgb_colors. This

class is limited to the app_server because of the access to the system palette for
|
||||
looking up the 32-bit value to each color index.
