[Marble-devel] Review Request 111499: GroundOverlay Rendering

[Konrad Enzensberger]

Hi Adrian,

the new ground overlay rendering does not work for images covering a smal area.
find attached a sample kml/image , additional see the two screenshots,
one shows this kml loaded by old marblewidget version, one shows this loaded with new
ground overlay rendering - it looks really ugly,

br, konrad

        By Adrian Draghici.
        Updated July 23, 2013, 9:41 a.m.

        Changes
Prevents rendering of GroundOverlays on post-colorized map themes in TextureLayer rather than MergedLayerDecorator. Adds a MacLaurin approximation for the Gudermannian function to be used for rendering in Mercator Projection. 

        Description 
This patch adds support for rendering GroundOverlays. A model with filtered GroundOverlays is saved in MarbleModel and used in TextureLayer, where the cache of GroundOverlays is handled. The actual rendering takes place in MergedLayerDecorator. 

        Testing 
Tested with multiple overlapping overlays, different rotation angles.
