Summary:
There are several reasons why I "re-wrote" the Glide effect:
* it doesn't work correctly because it suffers from undesired perspective distortions: {F5914378}
The worst part is that windows are distorted so much on multiple monitor setups that it's hard to say whether that's glide animation.
* window close animation is not quite intuitive: if the close button is
located at the top and I click it, I would expect that window is
rotated around the bottom edge, not the top; (IMHO)
* it's too much distracting when working on something for quite good
amount of time: e.g. when editing photos, which involves a big number
of different dialogs;
* there are issues with deletion of QTimeLine;
* windows are not gracefully released if some other effect grabs them;
* its code doesn't follow common coding style in KWin.
So, the "new" Glide effect is more subtle, it's possible to have
different rotation edges for window open/close animations, it doesn't
animate special windows(like audio volume feedback), the code is simpler
and readable. Yet, there are some issues with QTimeLine, which are
common to all effects in KWin anyway.

Summary:
Kdelibs coding style states the following about whitespace placement:
> For pointers or references, use a single space before '*' or '&', but not after
Source: https://community.kde.org/Policies/Kdelibs_Coding_Style#Whitespace
Also, putting a whitespace after ! is not common in KWin.
Test Plan: Switched between virtual desktops.

Summary:
When the Sheet effect was written, isModal worked only for Client
windows, not Deleted windows:
bool EffectWindowImpl::isModal() const
{
if( Client* c = dynamic_cast< Client* >( toplevel ))
return c->isModal();
return false;
}
so the Sheet effect had to track windows by using WindowInfo class, e.g.
class WindowInfo
{
public:
bool deleted;
bool added;
bool closed;
};
the biggest drawback of that method is that WindowInfo for each modal kept around
as long as those modals existed. It also was adding little overhead, e.g.
void SheetEffect::paintWindow( EffectWindow* w, int mask, QRegion region, WindowPaintData& data )
{
if( windows.contains( w ) && ( windows[ w ].added || windows[ w ].closed ) )
Things changed with a8160b3c31afa1db24084147ad4ce50cf3c0314a. With that
commit, WindowInfo kept only for modals that are currently being
animated, but isModal still worked only with Client windows, so
IsSheetWindow hack had been introduced.
Long story short: we don't need IsSheetWindow hack anymore because
isModal now works with Deleted windows.
Test Plan: Pressed Ctrl+O in Kate.

Summary:
KWin had Outline effect during KDE SC times, which had been removed in
KDE SC 4.11. With that effect, also showOutline and hideOutline signals
had been removed, making it impossible to write effects that show
outline. Yet, Outline enum value had been left.
Even though the Outline feature is useless nowadays, in order to keep API
compatibility, let's just deprecate it.

Summary:
Pointer constraints should become disabled when the TabBox is invoked. Since
the current client stays activated while TabBox is enabled and currently can
not be deactivated with the risk of regression as discussed in D13758, disable
all pointer constraining explicitly and enable it again when the TabBox is
closed.

Summary:
If the new pointer position is "off screen", PointerInputRedirection
just ignores that new position. So, pointer remains on its previous
position. In some particular cases, like reaching default panel, it
degrades desktop experience because one have to slowly move pointer in
order to reach what he/she wants.
This change addresses that problem by confining the new pointer position
to screen geometry.

Test Plan:

* Ran the following Python script
```lang=python
import dbus
bus = dbus.SessionBus()
effects_object = bus.get_object('org.kde.KWin', '/Effects')
effects_iface = dbus.Interface(
effects_object,
dbus_interface='org.kde.kwin.Effects'
)
names = (
'slide',
'pizza',
'cube'
)
supported_statuses = effects_iface.areEffectsSupported(names)
for name, supported in zip(names, supported_statuses):
print("%s: %s" % (name, supported))
```
Got the following output:
```
