		int	zoom
	)

pure virtual

This function is called after the presentation finishes redrawing.

Parameters

vi	The ViewInterface on whose behalf the request is made
cr	The context to with, the origin of the context is translated to be the same as the origin of the presentation.
presentationArea	the area that is to be drawn. The given `x` and `y` coordinates should map on 0,0 of the given context `cr`.
