Detailed Description

BackgroundColorPrimitive2D class.

This primitive is defined to fill the whole visible Viewport with the given color (and thus decomposes to a filled polygon). This makes it a view-dependent primitive by definition. It only has 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.
