Fix uninitialized ColorSceneLinear4f occuring in certain situations.

On gcc 11.3, Ubuntu 22.04 the default constructor for
ColorSceneLinear4f did not zero the r,g,b,a member variables. Replacing
the empty constructor with a default constructor circumvents this
problem (compiler bug? ) even though it *should* be more or less
equivalent.
