javascript - OpenLayers, Bing, continuous map layer -

i'm trying bing layer continuous in openlayers, cannot find solution. can see on illustration (http://openlayers.org/dev/examples/bing.html), when scroll map horizontally or vertically, layer not continuous google map (http://openlayers.org/dev/examples/google.html). it's quite weird when zoom out , map doesn't fit viewport leaving blank white background on left , right side. ideas?

thank you.

this illustration shows how accomplish horizontal repeat:

not sure how solve white background when zoomed out, not think openlayers supports this.
