Windows in workspace.clientList() are sorted in the map order. This
means that the minimize all script will try to activate the last mapped
window when unminimizing windows, which is a bit annoying.
This change ensures that the minimize all script doesn't activate wrong
window by minimizing and unminimizing windows in the stacking order.
It's not a bullet-proof solution though, but it should produce good
enough results.
Once in a while, we receive complaints from other fellow KDE developers
about the file organization of kwin. This change addresses some of those
complaints by moving all of source code in a separate directory, src/,
thus making the project structure more traditional. Things such as tests
are kept in their own toplevel directories.
This change may wreak havoc on merge requests that add new files to kwin,
but if a patch modifies an already existing file, git should be smart
enough to figure out that the file has been relocated.
We may potentially split the src/ directory further to make navigating
the source code easier, but hopefully this is good enough already.
