ToolTipAreas are often the critical path for mouse handling, since
hover events are not filterable from below in the item hierarchy.
When disabling tooltips also stops updating containsMouse code has
no way to adapt, since there's no API to read the pref from within
QML. This changes the implementation of the pref to only prevent
tooltips from being shown, but still continue to handle hover events.
We need to use a GLXFBConfig which matches the depth of the window
pixmap's depth. So far it used the GLXFBConfig of the GL context.
This worked fine for RGBA windows, but failed for RGB windows on e.g.
some NVIDIA drivers.
After this change the FBConfig of the context is completely ignored,
instead it tries to find a good FBConfig for a given depth.
Whenever a FBConfig for a given depth is found it's inserted in a
cache shared between all WindowThumbnails so that we don't have the
X roundtrips all the time.

The WindowThumbnail needs XCB_EVENT_MASK_STRUCTURE_NOTIFY on the window.
For this it needs to change the window attributes. But it needs to keep
the existing event mask to not break other code. Also it cannot remove
the event mask again, as there is no chance to know whether another
component requires STRUCTURE_NOTIFY.
This fixes the not updating items in the tasks applet as the event mask
needed for KWindowSystem got overwritten.

Port IconItem to native QSGTexture including the animation.
This will save constantly uploading a new texture to OpenGL throughout the animation.

All QQuickWindows share a default format. By setting a custom format
it overwrites the default and this results in a format without a
stencil buffer being requested resulting in possible rendering errors.
