That's a perfectly good way to do it; another is to draw stuff into a 
picture, using a picFrame rectangle of some size in the OpenPicture call, 
and then drawing the picture with a dstRect rectangle of a different size 
in the DrawPicture call.  QuickDraw will scale everything in the picture 
in such a way as to make the picFrame match the dstRect.
