Legend does not refresh map when layers switched on/off when using selection overlay

[chrisclaydon]

1. Create a layout with an MG map containing more than one layer.

2. Turn off a layer.

3. Select a feature.

3. Turn a layer off or on.

RESULT: Layer will not turn off or on.

Note: It looks like the selection overlay is re-drawn instead of the map.

Also, if you create a buffer on the layout, the buffer does not show up until you pan or zoom. Again, it looks like the selection overlay gets re-drawn instead of the main map image.

The logic for handling redraws when we have a separate query layer is not complete. We need to separate out drawing the query layer from drawing the map so that we don't need to refresh the map when selections change and we don't need to redraw the selection when the map changes.

(In [1636]) Re #149. Separate logic for drawing selection and map in the case of a separate overlay layer in MapGuide. Also remove the resize effect on the selection overlay layer as it causes a temporary visual displacement of the selection image that is quite disconcerting.

Closing.

This problem seems to be back in the latest code.

(In [1651]) Re #149, merge r1636 back in to trunk, somehow this change got reverted by me.

somehow I overwrote the change, fixed again!
