This primitive is defined to fill the whole visible Viewport with

the given color (and thus decomposes to a filled polygon). This

a valid decomposition if a valid Viewport is given in the

|
ViewInformation2D at decomposition time.
|

It will try to buffer its last decomposition using maLastViewport

to detect changes in the get2DDecomposition call.
