[Gimp-developer] Change size and ratio of Gimp Preview

[Nicolás Serrano Martínez Santos]

Thanks for the advice. I've tried using ZoomPreview and it adjust to  
the drawable ratio. If i create a rectangular drawable the widget  
will be rectangular, what i want (let's see if i can be clear) is to  
adjust the width and height of the preview widget. It's adjusted to  
the drawable ratio and the i don't managed to change it.
