Description

When using MapServer 4.8.1 as a wms source, layer labels change positions depending on the view. It would be nice to have an option to have uDig always refresh the entire screen for some layers to prevent labels from getting cut in half during a screen update.

There is a preference under windows>Preferences. I believe it is one of the Rendering preferences. (Tiling).

On second thought it should also be set on a layer by layer basis.

I am not sure I understand this request? I think what it is saying is that a layer property should be available to ask that layer.refresh( Envelope ) is modified into layer.refresh( null)

This would have the effect of causing the entire visible screen to be redrawn - rather than just a new segment of the screen that has just been pulled in by a Pan.

Note the TiledRendering system has this covered every which way (although I suspect we will get a few more labels duplicated since the tiles may be quite small?). We have tried to choose a good balance but experiment is possible.

Emily or Jesse could do this one quickly :-)
