Asks the window manage to move the window to the given position. Window
managers are free to ignore this; most window managers ignore request for
initial window positions (instead using a user-defined placement algorithm)
and honor requests after the window has already been shown.
Note: the position is the position of the gravity-determined reference
point for the window. The gravity determines two things: first, the
location of the reference point in root window coordinates; and second,
which point on the window is position at the reference point.
By default the gravity is GDK2.GRAVITY_NORTH_WEST, so the reference point is
simply the x,y supplied to move(). The top-left corner of the window
decorations (aka window frame or border) will be place at x,y. Therefore,
to position a window at the top left of the screen, you want to use the
default gravity (which is GDK2.GRAVITY_NORTH_WEST) and move the window to
0,0.
To position a window at the bottom right corner of the screen, you would
set GDK2.GRAVITY_SOUTH_EAST, which means that the reference point is at
x + the window width and y + the window height, and the bottom-right corner
of the window border will be placed at that reference point.
