Not sure wS is worth it, actually - I still get graphics issues with
e.g. steam

This is in line with what we do to clients that are set floating later on

This doesn't work currently as kwin seems to hand us the old screen size.

Appears to be working for now

This causes more problems than it solves (only part of the issues with steam)

This shouldn't actually happen

Ignored clients can't be tiled, ever - those properties don't change

Still sucks.

As Martin suggested - it really served no use in tilingmanager

This was caused by directly connecting the signal to the (desktop
specific) tiling object in a case of weird asymmetry.

Remove unused functions and consolidate others

It seems that windows can be both normal (i.e. not special) and a
dialog.

We only care that it is a dialog.

This requires delaying the first resize until after the window is shown

It seems that kwin doesn't create the pixmap early enough so we could
resize before that happens.

Somehow setting tiling_floating in addClient will crash kwin

This appears to crash kwin quite a bit

Keep windows that should be at the screenedges there, while allowing
squashing windows to be moved back to reveal the squashed ones.

The previous "fix" (8d7a5d3c) broke moving majorly

* Bugfixes

* Remove tabgroup handling

It currently doesn't appear to be possible to do otherwise, as

* tabGroupChanged is called for all clients in the tabgroup (at least
  once it's built)

* client.tabGroup is always undefined

This avoids an infinite loop (fortunately it'd be recursive, so the
stack would kill it)

* Bugfixes (including resizing)
* "Animate" window move and resize
* Actually retile windows after they added borders etc

Remove some unused or commented lines, fix a minor typo

This is now pseudo-animated, which is much nicer than an outline anyway

This didn't actually work before, but now we can handle clients getting
borders and some other stuff better

(Also simplify code)
