 Currently if we want to render an image of a map with any tiled base
 layers at any arbitrary scale, we have to use the RenderMap API.

 The problem with the RenderMap API, is that the background color is pre-
 filled into the image making it fully opaque and un-suitable for
 overlaying on top of another image.

 The problem with the RenderDynamicOverlay API (which is normally the API
 we would use in this case) is that tiled base layers are omitted during
 rendering.

 Attached is a patch that introduced a new behavior flag (RenderBaseLayers)
 for the RenderDynamicOverlay API, and a modification to
 RenderDynamicOverlay to include such tiled base layers if the new
 RenderBaseLayers is OR'ed into the behavior parameter.
