    Make BitmapColor inherit from / merge into Color · c34bb163
    Jan-Marek Glogowski yazdı
    BitmapColor itself is kept to distingish the Color usage as part
    of a color palette, which continues to store the offset in the
    blue value. The original special mbIndex handling is long gone
    since commit 1fefdd6f ("Alpha channel in BitmapColor - change
    bIndex to alpha"), so there is no data difference.
    This also results in the following changes:
    * now has a basic_ostream<charT, traits>& operator<<
      (that was my actual starting point... for an other bug fix)
    * there is a minimal difference for GetLiminance
      BGR(29,151,76) => BGR(28,151,77)
    * no more return values for Merge and Invert
      (previously returning *this)
    * replaces all GetBlueOrIndex with GetIndex
    This leaves one "problematic" part: the GetColorError handling.
    At first glance it should probably be virtual. The Color variant
    is less strict then the BitmapColor one - for whatever reason.
    BitmapColor is always used to search for the best match in a
    Palette. Currently I'm simply leaving both variants. Would be
    nice to have an explict for functions here.
