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:
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.

As it turns out, people don't like this kind of behaviour. Another
problem with sliding of docks is that pager goes away.
This change disables sliding of docks by default. One can enable sliding
of docks by checking "Slide docks" checkbox in slide effect KCM.
Yet, transition to/from virtual desktop with a window in full screen
mode doesn't look great but that's somewhat acceptable:

Summary:
Currently, effects like Maximize, Slide Back have problems with setting
WindowForceBlurRole. They store previous state of WindowForceBlurRole.
This is wrong. Instead they should either ignore previous state of
WindowForceBlur or refcount forced role.
There's no need for refcounting right now. For example, if several effects
force blur or background contrast, they are most likely in a conflict.
Please notice that the Desktop Grid effect uses the Present Windows
effect only to calculate transformations.
Some other problems with the code that sets WindowForceBlurRole:
* Maximize effect stores previous state of WindowForceBlurRole only
for one window. It ignores the fact that there could be several
active maximize animations;
* Desktop Grid/Present Windows/Slide back don't clean after themselves.
So, after using those effects for good amount of times, memory usage
will bump.
Test Plan:
* Enabled blur for Konsole
* Maximized Konsole
* Activated Present Windows
* Activated Desktop Grid
* Raised another window(to trigger Slide Back)

The main problem was that inside the effect there was manualVerticalAngle,
which did not represent the actual rotation angle of the cube during the
animation, but used to calculate the position of the reflection. The actual
angle was calculated on-the-fly and was not exposed outside.
Brief description of what the code does:
- variables currentAngle and verticalCurrentAngle now always represent the
current position of the cube. They are updated when one uses the mouse and
inside the rotateCube() method, which is called in prePaintScreen().
- two queues, animations (used for Start / Stop / Left / Right) and
verticalAnimations (used for Up / Down) are used for scheduling the animations
if i.e. user presses several keys in a row. The code checks whether the last
animation has finished (and thus we need to start a new one) inside
prePaintScreen() and postPaintScreen()
- when the animation starts, code saves the starting position of the cube
inside startAngle, startFrontDesktop and verticalStartAngle variables, which
are used to calculate the actual cube position during the animation later.
This is done by startAnimation() and startVerticalAnimation(), which also
calculates the QTimeLine curves needed for animation
