We would like a opacity/transparancy slider that can be implemented as a tool 
in the geoext-viewer

There is already something present in geoext for this: 
http://www.geoext.org/lib/GeoExt/widgets/LayerOpacitySlider.html. We need to 
adapt this tool.

See the example: 
http://kademo.nl/lib/geoext-viewer/trunk/geoviewer/examples/activelayers
through the concept of stacked active layers (new widget 
http://code.google.com/p/geoext-viewer/source/browse/trunk/geoviewer/lib/widgets
/ActiveLayersPanel.js) each Layer can be manipulated for opacity. Through 
configuration standard GeoExt OpacitySlider options can be set such as the 
slider can be made "aggressive" (respond immediately), use transparancy i.s.o. 
opacity etc.
