 /**
  * <b><code>TextureAtlas</code></b> allows combining multiple textures to one texture atlas.
+ * 
  * <p>After the TextureAtlas has been created with a certain size, textures can be added for
  * freely chosen "map names". The textures are automatically placed on the atlas map and the
  * image data is stored in a byte array for each map name. Later each map can be retrieved as
  * a Texture to be used further in materials.</p>
- * <p>The first map name used is the "master map" that defines a new location on the atlas. Secondary
- * textures (other map names) have to reference one texture of the master map whose position is used
- * to position the texture on the secondary map. This is necessary as textures share texture coordinates
- * and thus need to be placed at the same location on both maps.<br/>
- * The helper methods that work with geometries handle the DiffuseMap or ColorMap as the master map and
- * additionally handle NormalMap and SpecularMap as secondary maps.</p>
- * <p>The texture asset key name for each tile as well as its location inside the atlas is stored
- * and a texture with an existing key name is never added more than once to the atlas. You can access
- * the information for each texture or geometry texture via helper methods.</p>
- * <p>For each texture name you can also change the texture coordinates of a mesh or geometry
- * to point at the new locations of the texture inside the atlas if the geometries texture
- * exists inside the atlas.</p>

+ * <p>The TextureAtlas also allows you to change the texture coordinates of a mesh or geometry

+ * 
  * <p>Note that models that use texture coordinates outside the 0-1 range (repeating/wrapping textures)
  * will not work correctly as their new coordinates leak into other parts of the atlas and thus display
  * other textures instead of repeating the texture.</p>
+ * 
  * <p>Also note that textures are not scaled and the atlas needs to be large enough to hold all textures.
  * All methods that allow adding textures return false if the texture could not be added due to the
- * atlas being full. Furthermore secondary textures (normal, spcular maps etc. have to be the same size
- * as the main DiffuseMap texture.</p>
