 IMHO using Xrandr for screen resizing isn't a very good way of doing it.
Video players sometimes resize to quite small video sizes, and since other
apps react on root window size changes too, which could lead to such
unpleasant effects like desktop icons stacked in the upper left corner.

 Has some WM actually already some support for this? Given that '/* The
XF86VIDMODE_EVENTS code is far from complete */' (xc/programs/Xserver/Xext),
I don't see any way how the WM could detect vidmode changes - is there any?
There's nothing about it in the docs.
