[Inkscape-devel] do we need multiple toolboxes?

Do we really need multiple floating toolboxes? I think the toolbox should be treated as any other dialog, i.e. only exist in a single copy. If a user requests a toolbox for the current window, it's only created if it didn't exist, otherwise it's brought on top. This does not apply to docked toolboxes; these may exist one per document window. I think it's saner and more intuitive that way.

I have a patch that implements this. As a side effect it fixes some callback problems that resulted in crashes and failed asserts when I plugged in my unsinkability code into the toolbox (and quite probably some other problems too). If there are no objections I will commit.
