public abstract class InvWTAdapter extends Object implements InvWT
This abstract class can be used to facilitate the development of other classes that implement the 'InvWT' interface, because most of the trivial methods are already implemented.
If the default implementation of a method provided in this class does not suit a particular implementation of the 'InvWT' interface, the method can be overriden to implement the proper behaviour.
If the 'setImgResLevel()' method is overriden then it is very important that the one of this class is called from the overriding method, so that the other methods in this class return the correct values.

Note: Image resolution level indexes may differ from tile-component resolution index. They are indeed indexed starting from the lowest number of decomposition levels of each component of each tile.
Example: For an image (1 tile) with 2 components (component 0 having 2 decomposition levels and component 1 having 3 decomposition levels), the first (tile-) component has 3 resolution levels and the second one has 4 resolution levels, whereas the image has only 3 resolution levels available.
