Detailed Description

Used by a2dDrawingPart to decide what layers are to be rendered.

The a2dDrawing is checked via a2dCanvasObject::Addpending() etc. which layers contain objects. The array containing this information is stored seperate for each a2dDrawingPart. This is because each view can show different parts of a document, and one part can contain more layers then the other. This information is used to skip rendering layers which do not contain objects, or which are set invisible.
