The only one that does it differently is the DRM backend and it's just
an extension that takes GBM into account, otherwise it's effectively
copy-pasted code.
We need to register data types such as QVector<KWin::VirtualDesktop *>
both for QML and JavaScript scripts.
If you have no JavaScript scripts enabled, those container types won't
be registered and QML will fail to read properties such as
Window.desktops, which can result in already visible windows animating
opacity from 0 to 1 when opening overview effect.
To fix that, register all accessible data types in scripting apis in
Scripting::init().
We want floating tiles to be activatable, but also dismiss the effect by
clicking on the whitespace.
The current solution doesn't work as a floating tile that is in turn
split will pull focus from the children meaning those tiles can't be deleted.
Rather than special casing and z-manipulation we can simplify everything
by moving tile dismissal to the root of the effect and appropariately
propagating the event.

there is no practical reason I can see for why this should be limited to
stderr only. we are not reading or otherwise consuming stdout, we should
just pass it on.
Context: If a display is removed, the corresponding TileManager is removed with it. This in turn removes every one of its Tiles with it, and when a Tile's destructor is called, it attempts to find a new replacement tile for any windows it was previously managing.
However, if the Tile is removed because its corresponding TileManager has been removed, this has the potential to cause a segfault in KWin, causing it to crash (I suspect a possible race condition? but not sure).
This MR correctly evacuates custom tiled windows & migrates quick tiled windows upon output removal.
BUG: 465522
Use input device specific apis to change the position of the cursor. The
main reason to do so is to break the assumption that Cursor position is
the same as pointer position, which I would like to rely on later to
merge tablet and pointer cursors.
dmabuf buffers have the origin in the top left corner, so a texture with
attached dmabuf must have y inverted.
By correctly specifying the y inverted flag, we could leverage existing
infrastructure in kwin to handle vertically mirrored textures and make
simpler some projection matrix code in screencasting.
Even though the names seem to match, QtWayland maps button values
to enum values in ascendung order (as it does on X11). The wrong
mapping is usually not a problem because we send the native button
events to clients. However when the Qt names or values are used
for communication between KWin and a client this leads to
misunderstandings.
