RFC: winex11.drv: drag from X, drop to OLE (try 3)

[Damjan Jovanovic]

Hi

This is my third attempt at a patch for dragging from X and dropping
to Wine, with the more advanced OLE drag and drop.

This attempt doesn't add a public API to OLE and instead uses the
cross-process drag and drop framework implemented by commit
6d1ef3a6a64f0fabf05ce1bba5f0ec4373684786. The previous attempt was
http://www.winehq.org/pipermail/wine-patches/2007-August/042910.html.

I am not expecting this to get accepted yet, just posting to
wine-devel to get some feedback on the overall design.

Thank you
Damjan Jovanovic
