Make style.graphicTitle standards-conformant

[potter000]

Hello, I've recently been using OpenLayers to draw a map with a layer of markers, each of them being an external PNG image. I wanted tooltips to be shown on markers hover, and the easiest way to achieve that is to set a graphicTitle attribute for each marker (feature) style.

Though that works for FF, that does not work for other browsers (e.g. Google Chrome), 'cause the present behaviour is not standard-compliant. According to  http://www.w3.org/TR/2000/CR-SVG-20001102/struct.html#DescriptionAndTitleElements, "title" is a child element, while currently Renderer.SVG sets an attribute.

I have created a patch to resolve the issue. It leaves current behaviour (an attribute) while adding a child <title> element. I've checked it with FF 3.6, IE 7, Opera 10.63 and Chrome 8 (all on Linux except IE). Please consider this patch and let me know if it was useful.

I think this patch is correct and is already ready for review. This doesn't break any tests and it preserves backward compatibility for Firefox.

I think we'll need an agreement from this contributor.

Please feel free to do whatever you find necessary with this patch (if you mean this by "an agreement from this contributor."). I'm using trac for 1st time, so if any actions are required from me, let me know what I should do.

Sorry, but can you send you agreements to openlayers-cla at openlayers dot org. The address seemed to be the wrong one. Thanks again.
