Detailed Description

Contains the event distributor.

The event distributor exists of several classes which are combined in one templated distributor class. The classes are closely tight together.

All classes have direct access to each others members since they should act as one. (Since the buttons are a templated subclass it's not possible to use private subclasses.)

The mouse_motion class handles the mouse motion and holds the owner of us since all classes virtually inherit us.

The mouse_button classes are templated classes per mouse button, the template parameters are used to make the difference between the mouse buttons. Although it's easily possible to add more mouse buttons in the code several places only expect a left, middle and right button.

distributor is the main class to be used in the user code. This class contains the handling of the keyboard as well.
