Bridge methods are methods introduced by compilers in relation to met…

…hods that use generics. Various renderer related method trigger test methods for just bridge methods, but are never really implemented.

For example, the below interface code causes the coverage test before
this patch to expect the bridge generate(IChemObject object, RendererModel model)
method to be tested:

public interface IGenerator<T extends IChemObject>  {
  public IRenderingElement generate(T object, RendererModel model);
}

This fix now skips these bridge methods from coverage testing.

(Thanx to Arvid Berg for pointing me to the Method.isBridge() method!)
