Summary:
There were several reasons to rewrite the Minimize Animation effect in
JavaScript: to simplify code and to get rid of full repaints. One could
say that nothing prevents us from calculating the dirty region in
postPaintScreen or postPaintWindow and it is correct, but with the
scripting effects API the dirty region will be calculated for us, so we
can focus more on "what we want" instead of "how".
Visually, the "old" effect and the rewritten one look quite the same.
Except one tiny bit: if a window doesn't have an icon in the task manager,
it won't be animated. The reason for that is the purpose of this effect is
to show where the window will be after it's minimized, if the window
doesn't have icon in the task manager, one can't click at the center of
the screen to unminimize the window.
There is one significant change, the name of the effect was changed to
"Squash". If we put this effect and the Magic lamp effect under "Window
Minimize Animation" category (or if we add some "heading" label), then
the old name and the name of the category would "conflict". The new name
was suggested by Nate Graham and it very closely describes what the
effect does. "Scale" doesn't fit this effect because while a window is
being animated, its aspect ratio is not preserved.

XDG Toplevels can have a transient parent without having positional

Currently we set that we have a transient placement hint of 0,0 which
means the newly opened children go to the top left of the parent.
This new code paths treat child top levels as dialogs centering them to
the parent.

Summary:
Background behind some windows is not blurred because the invert effect
sets PAINT_WINDOW_TRANSFORMED. This essentially "turns off" the blur and
the background contrast effect unless we set the force roles.
Because the invert effect is a "post-processing"(not really) effect we
don't have to set that flag.

Summary:
For some historical reasons, the sheet effect uses animation duration of
500ms. In comparison to other effects that animate the appearing and the
disappearing of windows, 500ms is too high value for the duration.
As the title says, this change decreases the default animation duration
to 300ms. The new duration is more saner.
The opacity is animated to make the effect look smoother with the
shorter animation duration.

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.

Currently if a window flows off the right, we move the window back by
it's own width, leaving it floating at a random point.
For consistency we should be setting it so the right edge of the popup is on the right
edge of the screen.
So in the auto test for the "right border" case:
The screen is 1280 wide, and we open a 10px popup at 1279 the final X

Summary:
When using the natural layout algorithm with the fill-gaps option, a small
error (less than one) is introduced in windows' aspect ratio each time they are
enlarged due to floating-point roundoff.
Currently, the algorithm computes the width and height enlargement factors and
then attempts to enlarge in each of the four possible directions, repeating
until it can't enlarge any windows any further. Hence, this aspect ratio error
can be multiplied by up to four. Especially for small, long, and narrow
windows, this can result in a total error of greater than one by the end of
that loop iteration. If this occurs, on subsequent iterations the height
enlargement factor might then be computed as negative violating some of the
core assumptions of the algorithm and resulting in the loop iterating endlessly
until one of the window dimensions overflows, freezing the program for up to
several minutes.
To fix this, the height enlargement factor should be re-computed based on the
new width each time the window is enlarged, ensuring the error introduced in
the aspect ratio never exceeds one.

Test Plan:
The most reliable way to reproduce the freeze seems to be to activate the
desktop-grid effect while a tool-tip window is fading in.
Ensure desktop-grid is configured to use present windows, and that present
windows is configured to use the natural layout algorithm with the fill gaps
option selected.
The freeze is still intermittent, but using this method should be able to be
triggered within about 10 tries without this fix.
After applying the fix, the freeze has never been observed.

given transient is a transient for a given window so we can keep Deleted

Summary:
The Dim Inactive effect expects that the windowClosed signal always
proceeds the windowDeleted signal. But in some cases that's not the case.
If a window gets destroyed before becoming ready for painting, only
the windowDeleted signal will be emitted. In addition to that, KWin will
activate that window, which means we'll probably start a transition for
it.
Because this effect cannot terminate active transitions for such
windows, KWin can crash in postPaintScreen.
This change addresses the crash in postPaintScreen by adding extra clean
up stuff in the windowDeleted slot to make sure that there are no
transitions for deleted windows.
The proper fix would be to not emit windowActivated signal for windows
that are not ready for painting.

Summary:
If a modal window is closed and some alternative effect that animates
the disappearing of windows is enabled(e.g. the Glide effect, or the
Scale effect), the Dialog Parent effect can cause flickering of the
parent window because its animation duration doesn't match duration of
those alternative effects.
Also, if the Fade effect, the Glide effect, and the Scale effect are
disabled, the Dialog Parent will keep the parent window alive for no
good reason.
This change addresses that problem by adding keepAlive property to
`animate` function so scripted effects have more control over lifetime
of animated windows.
If both a modal window and its parent window are closed at the same time
(and there is no effect that animates the disappearing of windows), the
Dialog Parent will stop immediately(because windowDeleted will be
emitted right after windowClosed signal).
If both a modal window and its parent window are closed at the same time
(and there is effect that animates the disappearing of windows), the
Dialog Parent won't reference the latter window. Thus, it won't cause
flickering. I.e. it will "passively" animate parent windows.

Summary:
Previously when updating the state we would send a configure event with
the size 0,0. This means the client chooses the size. For regular window
this works as most toolkits treat this to mean the size that we
previously requested. It's not explicit in the spec either way.
For maximised windows it's a problem, the spec clearly states that when
maximised clients must follow the size given. Telling the client to be
0,0 doesn't make sense.
By always sending our last requested size we remove any ambiguity.
