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


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.
