In our application most of layers are static (Shape, VPF, drawings, etc)
which don't change frequently (only when projection, center or scale is
changed). We put those layer in BufferedLayerMapBean. Above them there
are several 'dynamic' layer - we use them to display moving tracks (from
radar source). Our fix allow us to dim all static layers and make tracks
better discernible over background.

The code is probably not available in CVS yet.
