Add rudimentary support for resizing.

- Currently only libnsfb's SDL surface supports resizing.
- Flickers like crazy while resizing.  Possibly because the SDL
  surface is not set to use double buffering.
- The internal widget library, fbtk, was never intended for this,
  as such it has no knowledge of how a widget should be positioned
  with respect to its parent.
  This means the top level window has to track everything and move
  them itself.
