Brecht Van Lommel 9498121463 Object API changes so these functions now require a scene as first argument: 
create_mesh, create_dupli_list, make_display_list and is_visible.

This is done in order to make these context independent as the RNA API should
be as much as possible, and to fix #21297 and #21719, where there was an
assumption from these functions that there is a scene in the context, which
does not work for external render engines exporting in a separate thread.

Also avoided using context in a number of other functions, ideally only UI/WM
type functions should use context.

I've updated the scripts in trunk, but the addons and external ones in
development will need updates too.

This script exports to X3D format.

Run this script from "File->Export" menu. A pop-up will ask whether you
want to export only selected or all relevant objects.
Known issues:<br>
Doesn't handle multiple materials (don't use material indices);<br>
Doesn't handle multiple UV textures on a single mesh (create a mesh for each texture);<br>
Can't get the texture array associated with material * not the UV ones;
