Basically this is a well known issue in wayland for globals. If bind
comes after destroyed, it will raise a invalid global error. The common
practice is to delay the destroy of global. Similar technique is also
applied to wl_output.

If the backend needs to apply custom logic when changing the transform,
it should override Platform::applyOutputChanges(); otherwise just update
the Output's internal transform state.
AbstractOutput is not so Abstract and it's common to avoid the word
"Abstract" in class names as it doesn't contribute any new information.
It also significantly reduces the line width in some places.
The API of SurfaceInterface was changed so it always maintains an opaque
region.
At the surface commit, if the attached buffer is opaque, the whole
surface will be marked opaque. Otherwise, the specified opaque region
will be intersected with the surface rect.
This is a patch to get the last two commits to work.
A larger problem to fix is that when the desktop grid size is changed in
the KCM by removing desktops, the internal grid dimensions are not
updated until system restart.
Fixed a bunch of bugs and polished the slide effect.
Plugged the slide effect into the new VirtualDesktopManager interface desktopChanging() to allow for mac os style desktop switching.
BUG: 448419 BUG: 401479
Added this interface to the VirtualDesktopManager. Realtime touchpad gestures update the interface to allow for mac os style desktop switching.
Also makes gestured switching use natural direction.

Input event flow has been refactored so all input events originate from
input devices.
The X11 backend uses InputRedirection so make it forward events to
relevant input device handlers.
Prefering alpha is needed for some interactions with video underlays; more
directly choosing formats with an alpha channel will be needed for overlay
planes, too.
The Window View effect is a companion effect for the task manager. It
provides the task manager a way to ask the user to pick a window among
windows identified by window ids passed to the activate() method.
The main motivation for adding this effect is to provide a QtQuick based
alternative for the present windows effect, which is needed to kill the
latter.
This change doesn't extend the overview effect to avoid repeating
mistakes of the past, i.e. adding too many (unrelated) features to the
present windows effect.
While the overview effect provides you a way to select windows, it's not
the only thing that it has. For example, it also allows changing virtual
desktops, etc.
On the other hand, the task manager doesn't need all of that. It only
needs to ask the user to pick a window among the specified windows, nothing
more.
As is, the window view effect is simply WindowHeap with a d-bus api slapped
on top of it.
The main motivation behind this change is to unify render target
representation across opengl and software renderers and avoid accessing
the render backend directory in order to get the render target.
GLRenderTarget doesn't provide a generic abstraction for framebuffer
objects, so let's call GLRenderTarget what it is - a framebuffer.
Renaming the GLRenderTarget class allows us to use the term "render
target" which abstracts fbos or shm images without creating confusion.
With these two actions being separate, RenderLoop can record the time spent
in endFrame (for example for multi-gpu transfers) without risking also recording
blocking swapbuffer calls, and endFrame can later be moved to output layer
