wrapDateLine is not supported by XYZ layers

[tomh]

Layer.XYZ does not support wrapDateLine and uses out of range tile coordinates beyond the date line.

The attached patch makes it respect wrapDateLine.

I would raise this in the Layer.XYZ component, but it doesn't seem to exist...

Can you please add a unit test?

Patch updated against current revision. I modified tests because they were displaying an "undefined" message. I also set "wrapDateLine" to true by default for the OSM class.

Tests pass on FF3.6 and Chrome 9. Please review.

Thanks Pierre and Tom. Please commit.

Pierre, before commit could you please set wrapDateLine to false in the mobile-drawing.html example, to prevent issues with drawing across the date line? Thanks.
