[Laszlo-dev] scaling the coordinate system of a drawview

Right now, now resizing a view causes it to clip the canvas to the same 
size.  We might want to add a 'resizable' option to drawview that turns 
this behavior off, if only to address this issue:
http://jira.openlaszlo.org/jira/browse/LPP-4836

If you're going to be DHTML-only, you can use the scaling APIs directly:
http://developer.mozilla.org/en/docs/Canvas_tutorial:Transformations#Scaling

<method event="oncontext" args="c">
   this.context.scale(0.75,0.75);
   ...
</method>

It would be great to expose scaling in a cross-runtime way, perhaps via 
stretches.  Canvas scaling looks a lot like the movieclip scaling APIs...
