[PATCH] zoom.js: change zoomGraphObjDrawSelection behavior to highlight all the graph vertically

[Gildas Le Nadan <gn1 (at) sanger.ac.uk>]

This patch change the behavior of the zoomGraphObjDrawSelection function 
to vertically highlight the graph on the whole of its height, instead of 
just a small box with the starting/actual coordonates.

With this new behavior, users are not surprised by the new graph not 
starting with the exact coordonates they have specified (i-e in X *and* Y).

Cheers,
Gildas
