Mathias Gumz e7bfc63932 Improve calculation of brighter colors 
The old code did not brighten up "pure" colors like "red", "green" and "blue"
at all. The new code use a different precomputed LUT which is based upon
simplified vector math, see the comments in FbTk/ColorLUT.cc

// math behind:
//
// rgb-color-space forms a cube. to make
// something "brighter" one has to nudge a
// given color towards "white" (255, 255, 255).
// we use simple vector math to do this:
//
// (nred ) (red ) ((255) (red ))
// (ngreen) = (green) + s * ((255) - (green))
// (nblue ) (blue ) ((255) (blue ))
//
// this approach is better than just multiplying
// a given color by a factor (ColorLUT::PRE_MULTIPLY*)
// example:
//
// brighten_via_premultiply_*(#ff0000) = #ff0000
// brighten_via_brighter_4(#ff0000) = #ffef3f
//
// right now the calculation of 's' is pretty
// straightforward: it is just 1/nth of the length
// of the vector-component. a more precise approach
// would calculate the length of the vector via
// sqrt(red * red + green * green + blue * blue) and
// scale that value down, allthough this would
// need either adhoc-computation or a more advanced
// lookup-table. right now the simple approach is
// sufficient.
//
// to make a color "darker" one has to nudge the
// color towards "black" (0, 0, 0). the formula
// from above changes to
//
// (nred) = (0) + s * ((red) - 0)
// ...
//
// which simplifies down to (s * red) .. which is
// covered by PRE_MULTIPLY_0_75 already.
