Kenneth is absolutely right, this is important for a couple of reasons
- when dealing with tiled maps, especially, you want to be able to
draw an untiled overlay with just the selection. I'll discuss with
Mike and see if we have started anything for this.

Actually, in MapGuide OS 1.2.0 the selection is a part of the image.
So any selection/de-selection will require the map to be redrawn
completely.
In MGOS 2.0.0 there was an optimization that enables an application
to retrieve the selection as a transparent PNG.
While the transition effects in OL 2.6 will visually minimize the
flickering, I would say that supporting the selection as a separate
image would be of great use in fusion.
This is especially true when the underlying layer contains complex
rasters.
I have emulated the seperate layer for MGOS 1.2.0 by keeping a dummy
copy of the map where I turn on all the layers, select, and turn all
layers off.
The dummy map has transparent background, and thus renders as just
the selection.

Here is a recent post on this.
------------------------------------------------
v1.1 of Fusion will incorporate v2.6 of OpenLayers which should
eliminate this problem and also gives us smooth transition effects
for zoom and panning. This has already been added to the trunk
version of fusion.

Subject: [mapguide-users] Fusion map insists on refreshing map on
selection,and clear selection...
Just wondering if there's a way to stop fusion maps from redrawing
the map everytime a user selects / deselects something? This
doesn't happen using the AJAX browser...does this happen for anyone
else?
