/**	Base class for user-defined controls.
	Like double-buffering we write the windows contents
	to an image and finally transfer the entire image
	to the device context.
	Additionally we keep the image between the paint events
	and rebuild the image only if necessary (data to show
	has changed).

	When the frame containing your view becomes invisible
	(frame iconized or hidden) you should use the ReleaseBuffer()
	method to decrease the memory footprint of the program.

	In your derived class, call the Dk4WxControl constructors from
	the constructors.
	From Create() call Dk4WxControl::Create().

	You should also use DECLARE_DYNAMIC_CLASS() and
	IMPLEMENT_DYNAMIC_CLASS().
