Summary:
Currently, there are a couple of issues with sizeForClientSize(). First
of all, we have a method called clientSizeToFrameSize() which does similar
thing except applying geometry constraints and checking window rules. The
other issue is that sizeForClientSize() is doing a bit too much, it checks
window rules, it applies a bunch of geometry constrains. Sometimes it
does not perform conversion between client sizes and frame sizes!
This change attempts to address those issues by replacing sizeForClientSize
with two similar methods and changing semantics of some methods of the
X11Client class.
The most significant difference between sizeForClientSize() and the new
methods is that neither constrainClientSize() nor constrainFrameSize()
check window rules. This is up to users of those methods. In many places,
we don't have to check window rules because we check isResizable(),
which returns false if the frame size is enforced by a window rule.

Summary:
Qt has its own thing where a type might also have corresponding list
alias, e.g. QObject and QObjectList, QWidget and QWidgetList. I don't
know why Qt does that, maybe for some historical reasons, but what
matters is that we copy this pattern here in KWin. While this pattern
might be useful with some long list types, for example
QList<QWeakPointer<TabBoxClient>> TabBoxClientList
in general, it causes more harm than good. For example, we've got two
new client types, do we need corresponding list typedefs for them? If
no, why do we have ClientList and so on?
Another problem with these typedefs is that you need to include utils.h
header in order to use them. A better way to handle such things is to
just forward declare a client class (if that's possible) and use it
directly with QList or QVector. This way translation units don't get
"bloated" with utils.h stuff for no apparent reason.
So, in order to make code more consistent and easier to follow, this
change drops some of our custom typedefs. Namely ConstClientList,
ClientList, DeletedList, UnmanagedList, ToplevelList, and GroupList.
Test Plan: Compiles.

Summary:
In order to properly implement xdg_surface.set_window_geometry we need
two kinds of geometry - frame and buffer. The frame geometry specifies
visible bounds of the client on the screen, excluding client-side drop
shadows. The buffer geometry specifies rectangle on the screen that the
attached buffer or x11 pixmap occupies on the screen.
This change renames the geometry property to frameGeometry in order to
reflect the new meaning assigned to it as well to make it easier to
differentiate between frame geometry and buffer geometry in the future.

Summary:
Currently each managed X11 client is represented with an instance of
Client class, however the name of that class is very generic and the
only reason why it's called that way is because historically kwin
was created as an x11 window manager, so "Client" was a sensible choice.
With introduction of wayland support, things had changed and therefore
Client needs to be renamed to X11Client in order to better reflect what
that class stands for.
Renaming of Client to X11Client was agreed upon during the last KWin
sprint.
Test Plan: Compiles, the test suite is still green.

Summary:
Because KWin is a very old project, we use three kinds of null pointer
literals: 0, NULL, and nullptr. Since C++11, it's recommended to use
nullptr keyword.
This change converts all usages of 0 and NULL literal to nullptr. Even
though it breaks git history, we need to do it in order to have consistent
code as well to ease code reviews (it's very tempting for some people to
add unrelated changes to their patches, e.g. converting NULL to nullptr).

Summary:
So far we were following a bit unique and rare doxygen comment style:
/**
* Contents of the comment.
**/
Doxygen comments with this style look balanced and neat, but many people
that contribute to KWin don't follow this style. Instead, they prefer
more traditional doxygen comment style, i.e.
/**
* Contents of the comment.
*/
Reviewing such changes has been a bit frustrating for me (so selfish!)
and for other contributors.
This change switches doxygen comment style in KWin to a more traditional
style. The main reason for doing this is to make code review process easier
for new contributors as well us.

Summary:
Currently popups get positioned once at the initial configure, to set
the correct size and again when they are mapped.
Toplevels are currently only positioned when they are mapped. This works
for all cases where the the toplevel defines its own size, but not if
the window should have an initial size set by the placement strategy or
window rules. Most notably the maximised placement strategy used on
plasma mobile.
Being out of sync and resizing later currently causes a positioning bug
when plasma mobile is used with XdgShell.
This patch repositions all top levels that don't have a position set
through the plasma interface.

Summary:
placeIn did not handle the case for a popup not having had the size
already set and only being available via
m_xdgShellPopup->initialSize(). This is needed if we want to call placeIn
at the correct time, before the window is mapped.
There was also a logic bug when sliding popups. We called the
confusingly named setX thinking it would be move the popup keeping the
width the same. In practice it moves the left edge keeping the right
position the same. This wasn't an issue as the size was
discarded.
Handling the resize constraint is not yet done, but it should now be
even more trivial.

Summary:
So far transients were placed anywhere on the screen. This behavior was
inspired from X11 where context menus were able to overlap any other
window and use the complete screen area. On X11 context menus and
similar windows are override redirect and thus above all windows managed
by KWin.
On Wayland, though, context menus and similar and windows just like any
other window and thus follow stacking constraints like the parent
window. A context menu is stacked just above it's parent and is
(normally) below any panels. This resulted in problems that context menu
are stacked behind the panel with unreachable options.
This change changes the placement for transients to use the
PlacementArea instead of a screen geometry. Thus the transient does not
render behind the panel. Only in case of a fullscreen the struts are
ignored.

Summary:
Support XDGShell Positioning. This gives a client a lot more control
over where the popup will be placed as well as control over how to
handle constraints. i.e what to do if the popup doesn't fit.
trasientOffset was replaced with a method on the client as semantically
it's the role of the client to handle constraints.
Both slide and flip constraint adjustments are implemented. Resize
constraint adjustment will be handled in a future patch.
WlShell is handled by treating it as 1x1 sized anchor with slide
constraint adjustment.
Test Plan:
Manual test of a client implementing xdgpopup exists in kwayland
Extensive unit test here

A transient window should always be visible on the current screen.
This change ensures that a transient is always placed in a way that
the transient window is visible on the screen ignoring the transient
offset hint if it has to be.
Unfortunately QtWayland doesn't set the transient hint correctly:
a sub menu is a transient to the main window and not to the parent
menu resulting in quite off positioned menus, see:
https://bugreports.qt.io/browse/QTBUG-51640
Need to add client pos to the transient's position. The offset is
relative to the parent surface, but the client doesn't know about the
size of the decoration, thus KWin needs to add it.
Methods are no longer virtual. The only x11 specific usage in these
methods (resizeInc) is replaced by a virtual method. Default resize
increments is QSize(1,1) for AbstractClient.
Method no longer virtual and only implemented in AbstractClient.
The implementaton works in a generic way nowadyas.
Added an autotest for the basic packTo behavior for packing against
a screen border. Packing towards other clients still needs adjustments
in the Placement code.
AbstractClient::mainClients is virtual and overriden in Client,
allMainClients has only a common implementation in AbstractClient.
In activation.cpp we still need one case where a temporary ClientList
needs to be constructed. Once transients are fully migrated that should
be removable again.
A transient ShellClient has an offset position to the parent surface.
Use this to position the ShellClient properly.
This fixes the random placement of menus.
