[vtkusers] Write an image size different from render window size

[Chris Alvino]

It seems that the magnification factor is hard coded to be the same for x and 
y.  Thus, what you want isn't possible without making your own filter.

Thus, the best way to do this might be to make your own vtkWindowToImageFilter 
class such as vtkWindowToImageFilterWithAspectRatio or whatever you want to 
call it, and make separate magnifications for x and y, then change the member 
function: vtkWindowToImageFilter::RequestData so that it works properly.

Someone else might have a better way.
