>   class BitmapEffect : public BitmapEffectBase

    Author:     Alex_Bligh (Xara Group Ltd) <camelotdev@xara.com>
    Created:    12/10/1994
    Purpose:    Base class for all bitmap effects

This class is intended to provide a usefully organised chain of BitmapEffectAtoms to the user.
The chain may be of length 1. The user should be able to use all of these classes.

All BitmapEffects should be derived from this class.

Though this class has nothing in it at the moment, it should have things to register it with
the main list, to read the format of parameters etc. It's also useful for as a pointer type,
i.e. the rest of the program should use BitmapEffect * when they want to refer to a bitmap
effect.
