No longer needed in a Plasma2 world as the components have a thumbnail
component, so the hack to go over KWin to render the thumbnails is no
longer needed.

By not using a QQuickView it becomes possible to just use a
PlasmaCore.Dialog or a Quick.Window in the TabBox qml and thus it's
possible to simplify the qml code.
To support this a new SwitcherItem is introduced and exported to QML.
It's a simple QObject providing all the properties which used to be
exported to the root context. A declarative TabBox is expected to
use one of these items. The C++ side finds the Switcher and for that
supports the case that the SwitcherItem is the rootItem or a child
item.
A declarative TabBox has also to create a QQuickWindow, e.g. a
PlasmaCore.Dialog. The visibility of that window should be controlled
through the visible property on the SwitcherItem. The underlying C++
implementation assumes that a TabBox only uses one window (it needs to
get destroyed once it's hidden and included in highlight windows).
Thanks to this change it's no longer needed to reload the TabBox
whenever it gets shown or the alternative TabBox gets shown. Instead
the same QML script can get reused. Other created switchers are ignored
as the visible property won't be changed to true.
The modalActionSwitch was used to disable all of KWin's actions during
Alt+Tab. This is not needed as Alt+Tab uses a keyboard grab and thus
no action will be triggered anyway.
Furthermore the functionality had been broken for years. The effects
use an own KActionCollection so their actions aren't considered and
neither the scripts.
Client used to have dedicated methods for different icon sizes instead
of combining all pixmaps into one QIcon. This resulted in various parts
of KWin having different access to the icons:
* effects only got one pixmap of size 32x32
* decorations only got the 16x16 and 32x32 pixmaps combined into a QIcon
* tabbox could request all icon sizes, but only as pixmap
Now all sizes are available in one QIcon allowing to easily access the
best fitting icon in a given UI.
It's basically a run of the port-cmake.sh script in here, mostly the changes
are the following:
- Using KF5::* targets
- Using the proper macros, following recent developments in frameworks
Not the best solution, but at least TabBox works each time it's invoked.
It doesn't make much of a difference as the QML is reparsed anyway at
each show.
Our back shortcut is registered as Alt+Shift+Backtab but our converted
Qt key coming into the test method is Alt+Shift+Tab. The logic so far
made this always fire for the normal Alt+Tab shortcut as at some point
the Shift modifier gets removed to do the test.
To handle it properly we first have to extract all the modifiers to just
get the key. If the key is Tab, we replace it with Backtab, combine it
with the extracted mods so it will be Alt+Shift+Backtab which matches
the registered shortcut.
The existing backtab solution can probably be removed and is clearly
wrong as it uses the keys as flags which they aren't.
