Oh.  The cutting edge "to be released these days" version.  That means
it takes at least one year (probably more) until most users will have
that, so it is a bad idea to drop VidMode support quickly ...

Yes.  xawtv deals with this by moving both viewport and application
window to the upper left corner and making the window size equal the
viewport size, so xawtv fills exactly the visible area.

The _NET_WM_STATE_FULLSCREEN way this doesn't work ...

Thats probably the better way to go in the long run.  Unfortunaly it
doesn't help to fix the "fullscreen @ 640x480" issue *now*.
