A window id generated by WaylandServer may reference an X11 window
with the same id, which can result in undefined behavior.
The main reason why we needed windowId() was because of the task
switcher. However, since tabbox uses internal ids now, the window id
property can be dropped.
For builtin effects the information comes from the EffectData struct.
For plugin effects the X-KDE-ConfigModule key is read from the plugin metadata.
For plugins that do not yet make use of it we fall back to the old way.
For scripted effects this is empty since the config is loaded in a different way.
Add a new field to EffectData that stores an effect's config module.
We currently determine an effect's configModule using KPluginTrader and the X-KDE-ParentComponents metadata.
IMO it's much more straight forward to let the effect specify its config module directly instead.
Since some people apparently liked the old behavior of moving minimized
windows to the end of the focus chain, let's let them have it if they
set a hidden config option:
`MoveMinimizedWindowsToEndOfTabBoxFocusChain=true` in the `[TabBox]` group
of the kwinrc file.
We can add a UI for it later if needed.
BUG: 427840

Surface ids are not unique across clients. If the underlying surface of
an XdgToplevelClient is replaced with an Xwayland's surface, you may see
weird results such as a desktop window having the contents of an X11
window or even worse a crash.

Listen to logind for resume notification and turn the outputs on when it
happens, much like we do when pressing a key.
This way laptops come back on when the lid opens.

Once the main surface has been unmapped, we are no longer interested in
any changes that indicate that the window quads cache should be discarded
This also fixes a bug where the scene holds a subsurface monitor object
even after the associated window has been destroyed.
QGraphicsRotation and Scale are QObject wrappers. It's not useful in
data structures where we're creating mulitple of these every frame. It's
large enough to appear in hotspot as taking over 1% of a regular frame.
We don't even use the QGraphicsRotation mapping inside scene for a
reason, so it's not giving us much.
It's technically an API break in libkwineffects. Pragamatically no-one
would use these. We also lose QGraphicsScale's origin, but we never
exposed this in PaintData's public header.
Since commit commits.kde.org/plasma-workspace/378309e666f52fc436c75648a9e6ad7d5dcbacdf
ksmserver sets a desktopname when restoring applications. This causes the effect
to draw above the splash windows while no cursor is visible.
We want to multiply the width/height by scale weather or not we are
using GLES or not, otherwise this will only provide part of screen when
used with e.g fullscreen screenshot.
By default, the rules list moves to the hightlighted item
(the one being edited) with a constant velocity. This can
be too slow when the list contains hundreds of items.
By setting `highlightMoveDuration` we set a maximum limit
for this animation.
BUG: 428139
If window thumbnails have to be downscaled, it's up to the application
what filter must be used. Also, we don't really use the lanczos filter
because both x and y scale factors are 1.
