kwin/autotests/tabbox/test_desktopchain.cpp
Vlad Zahorodnii 1fb9f6f13a Switch to SPDX license markers 
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.

In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
