wfs layer hangs firefox when zooming

[tschaub]

Though I don't have a live setup to demonstrate it on, I've reproduced the problem that is described by Steve ( http://www.nabble.com/Re%3A--OpenLayers-Users--Work-around-for-bug--541----p9798435.html)

On Windows Firefox, call to rendererRoot.setAttributeNS(null, "viewBox", extentString) is taking forever. After hours of browser crashing, I've determined that it can be resolved by clearing the renderer before setting this attribute.

The following patch moves the already existing renderer.clear call in the WFS layer's moveTo above the moveTo call to the superclass.

I have no idea why this works - or didn't work before. A browser bug I'd say.

Three cheers for tim! hip hip hooray! hip hip hooray! hip hip hooray!

It's likely that this is actually a symptom of #669, rather than something we actually need to do. If you could check it out and see if you can get it to happen again *without* this patch, I'd appreciate it.

In testing, I was able to confirm that this is fixed with the patch for #669. Marking this as duplicate unless we get another report.
