My document is zoomed so that the whole thing fits within the
application window. this wastes screen real estate; I'd like to
have the document more or less in the upper lefthand corner of the
application window (rather than centered). This will let me float
my palettes in the unused part of the screen, i.e. the "cutting
mat". Other applications let you use the hand tool to position the
document anywhere within the view, regardless of zoom level.
