Review request for Marble, Dennis Nienhüser, Torsten Rahn, and Thibaut Gridel.


Changes
-------

Hi Dennis,
Thanks for review :) . I have updated the patch.


Repository: marble


Description
-------

Modifications:

1. Added support to specify highlight color in dgml file.
2. Highlighting is done in the following way:

-> Input handler emits mouseClickGeoPostion( qreal lon, qreal lat, GeoDataCoordinates::Unit unit ) whenever a click 
   is detected on map.
   
-> Signal mouseClickGeoPostion(..) is connected to the signal MarbleMap::announceMouseClick(..) which
   further triggers the slot GeometryLayer::hadnleHighlight(..) which iterates over the tree model to find the        
   placemarks, from all GeoDataDocuments in which any of its style map has an entry for highlight styleId, which
   were under mouse when the click event happened.
     
-> After searching for all such placemarks GeometryLayer::hadnleHighlight(..) emits signal
   announceHighlight(QVector<GeoDataPlacemarks*> which is caught by GeoGraphicsScene to execute the slot
   GeoGraphicsScene::applyHighlight(QVector< GeoDataPlacemark* > selectedPlacemark).
   
-> GeoGraphicsScene::applyHighlight(..) we find all GeoGraphicsItems for a plcamark and execute
   GeoGraphicsItem::setHighlightStyle( GeoDataStyle *highlightStyle ) for each graphics items if the corresponding 
   placemark's style url is set to a style map which has a entry for highlight styleId.
   
-> GeoGraphicsItem::setHighlightStyle(..) assigns this style to GeoGraphicsItemPrivate::m_highlightStyle makes 
   GeoGraphicsItemPrivate::m_isHighlighted true. m_isHighlight decides which style ( normal or highlight ) to use
   to paint the graphics item.


That's it . Need feedback :)
