When a window goes away it was stoppping translucencyWindowTypeAnimation
and translucencyInactiveAnimation but any translucencyMoveResizeAnimations
was hanging there forever, causing ghost windows
BUG:439332
Imports come at a big cost when they're unused.
Also we shouldn't be importing WindowView from a different plugin. If
that effect is disabled it meant tileseditor would fail to load.
BUG: 464970
If there's windows and we're not searching, we don't need the
PlaceholderMessage. So only create it when we actually need it to reduce
the time needed to activate the effect.
We don't need the features of Repeater here and can instead just use an
Instantiator, which allows us to use asynchronous creation for the
window delegates, reducing the time needed to activate the effect.
Backdrop effects such as blur and background contrast have to be in the
front of the effect chain because they need to work with background
before the window is painted on top.
Hopefully it's going to fix panel popup blinking visual artifacts.
The subdivided grid used by these effects doesn't account for pixel
alignment. If we force the generated WindowQuads to be rounded, the
quad's sizes no longer match the texture sizes, which results in blurry
rendering.

There are cases where GLVertexBuffer::map will return null (as seen in
kwinglutils.cpp:1816) which does happen (as seen in the backtrace of bug
462017)
Make sure we don't call the null map in that case.
BUG: 372305
In this branch a new animation is being started, so a ref-guard needs
to be the same as in the similar branch for starting minimize animation
in the slot above.
WindowPaintData contains two projection matrices -
screenProjectionMatrix and projectionMatrix. I'm not sure why we have
two.
screenProjectionMatrix is initialized by the scene. While
projectionMatrix is usually updated by the effects. The two are not in
sync.
On the other hand, OffscreenEffect takes into account only
screenProjectionMatrix. It means that if a window is transformed by two
offscreen effects, the final result is going to be broken because
an OffscreenEffect must use the projection matrix specified by another
OffscreenEffect, which it doesn't.
This change cleans up projection matrix properties in WindowPaintData,
so there's only one projection matrix property. With that, offscreen
effects can be properly nested.
BUG: 462876
The focus outline that highlights the active virtual desktop in the Overview effect, as
well as the half-transparent outlines that are around the other virtual desktops, cover
2 pixels on every side of every virtual desktop thumbnail.
This is because an invisible rectangle is used that has the same size as the thumbnail
and has a colored border, but borders are always drawn on the inside of QML rectangles,
so content in the thumbnail is covered up. Therefore, the width of the rectangle has to
be slightly adjusted to account for the thickness of the border.

In the Overview effect, pressing the space bar doesn't always insert a
space character into the search field as one would expect; when the text
in the search field matches any windows, it instead activates the
highlighted window. At other times, it does insert a space as expected.
This behavior is unpredictable and unintuitive, so this commit fixes the
issue by intercepting the key input event and inserting a space when the
search field has focus. In this state, the highlighted window can be
activated using the enter/return key. When the search field doesn't have
focus, a press of the space bar will continue to activate the selected
window.
In most places, it's actually not needed and we actually provide wrong
damage region at the moment anyway. In long term, it would be great to
drop the Window::damaged signal.
Fullscreen windows are most likely games or videos, where the blend effect is an
annoyance that freezes the screen for a moment when a accent color change is triggered
in the background.
