when creating charts, by using a Primitive2DContainer&& parameter in the GroupPrimitive2D constructor, which forces the call sites to pass a temporary, and at most call sites, we can std::move in an existing local variable.

|
|
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.
