As I understand it, leftmove and rightmove anchor the left and right sides
of the child to the left edge of the parent, and topmove and bottommove
anchor the top and bottom to the bottom edge. Leftmove and topmove could be
tricky to implement if you're using gtk boxes, but rightmove and bottommove
should just require you to store the height and width of the canvas so that
when it changes, you can apply the same change to the height, width, or
both of the appropriate child controls.
