i'm not sure this is the reason. a lot of Windows stuff i've seen doesn't
actually resize the contents of the window until the user finishes resizing
the window frame.

whatever, low-level support for double-buffered drawing is long overdue.
the change to gint coordinates makes sense too. from my point of view,
the scrolling changes are less of a priority, and problems there should be
ameliorated at least in part by double-buffering.

i'm not sure i'd have the two suggested routines, though. why not have
this done by default, with a flag to turn it off, rather than make it
necessary for people to explicitly use double-buffering?

on the subject of scrolling, will the set_scroll_adjustments stuff go into
GtkWidget? that would be nice.
