This is the basic class for simple, animated primitives. The basic idea
is to have an animation definition (AnimationEntry) who's basic
functionality is to return a state value for any given animation time in
the range of [0.0 .. 1.0]. Depending on the state, the decomposition
calculates an index, which of the members of the child vector is to
be visualized.
An example: For blinking, the Child vector should exist of two entries;
for values of [0.0 .. 0.5] the first, else the last entry will be used.
This mechanism is not limited to two entries, though.
