That might work for sketching, when you start an entirely new drawing  
and do not care for matching up with pre-existing content. In my  
scheme both the x and y of the mouse cursor would be used. To take  
your example, if you want to draw somewhere about bottom-center of  
the screen, you would place the mouse cursor with your finger where  
the first stroke should be, and then start drawing with the pen in  
about the same location on the tablet. This would essentially be the  
same behavior as what you suggest, but it would be more precise.

I agree this proposed behavior might be a little unexpected for  
anyone who worked with a graphics tablet before, but I imagine it to  
be easy to get used to.

Involving the grabby-hand keys is a nice idea. However, I'd rather  
let it scroll the "virtual paper" you are drawing on. This would be  
consistent with the normal use of the grab keys, and give you a  
virtually unlimited scroll area. Moving the outline would be limited  
by the screen size.
