Re: GPL, Lots of opensource apps use the Windows API, there shouldn't
be any problems releasing this as GPL unless you copied someone elses
non-GPL code it should not be a problem.

IANAL: If the sample code doesn't have a license I would consider it
to be reference/documentation, after all MS cant expect to own part of
every app that uses their thumbnail example reference as a basis.

So I think its safe to release as GPL2 & eventually commit to blender/trunk.
