[Drawkit] Zoom to bounding box

[Michael Caron]

I did see in GCZoomView that there was something called "ZoomToRect".  
It didn't work as I expected it to, however. I'm loading a document  
from an archived state and when I try to look for the current drawing  
view from the DKDrawingView class method "currentlyDrawingView", I get  
a nil back. How does one get the current view so that I can do one of  
these ZoomToRect calls?

In the end I just decided to crop the drawing to the shape. I'm new to  
the framework, so my implementation is probably a bit crude. I keep an  
array of the drawable objects in my drawing so that I can translate  
them to new coordinates after resizing the drawing to the size of the  
bounding box. To translate all the objects, I just used the -(void)  
DKDrawableObject offsetLocationByX:byY: method.

I had tried to use the AffineTransforms, but they didn't appear to do  
anything. Is there a special way to use those? After you apply a  
transform to all objects in a layer, is there something else you have  
to do?

Cheers,
Michael
