When using gnome on small screens, sometimes a preference dialog or
application window will be too large to fit on the screen. Many times this
conceals buttons such as "ok" and "cancel". They typical solution is to use
the alt+drag method to move the window so that the top portion of it goes
off the top of the screen. Metacity (as of 2.4.34) does not allow the user
to forcefully move a window in this way. Combined with the fact that some
such windows do not allow for window resizing, it makes for a somewhat
frustrating experience.

I sympathize with the idea of keeping the window titlebar within the
desktop space. However, there are certain cases where this is annoyingly
restricting.  Perhaps a gconf setting to turn this off would suffice, or
some sense of "edge resistance" or snapping so that for most cases, the
effect is the same.

For my particular case, I am using a sony picturebook with a 1024 by 480
screen. Many dialogs are taller than 480 pixels. Most of the time I can get
away with resizing the dialog or hiding the panel temporarily, but it would
be nice to just be able to move a window up so that I can see the buttons
at the bottom.
