The pointing finger cursor is used to show that a piece of text is a
clickable link, and it is inappropriate to use it in other contexts.
Regular UI elements that do something when single-clicked continue to
use the standard arrow cursor in other contexts, so let's follow that
convention in the Present Windows and Desktop Grid effects too.

This commit removes the separators lines below "scale method" and
"rendering backend", options here shouldn't be separated since they
are all related to eachother.
Currently, each effect's list items expands when you click on any
non-interactive part of it, but it does not collapse when you click on
it again.
With this commit, now it does.

Makes for an odd decoration.
We generally will not have an app_id in the cases where we are creating
a token just in case it's necessary down the line.
If a client already has powers to move clients around, let them also
activate using the right protocols as well.
This is useful to be able to implement SNI or Notifications where the
shell doesn't get full surface activation when interacting with it.
This hack was added in the past to prevent the combobox from being
pushed out of view when the label next to it was very long, as it can be
in certain languages. However it had the effect of making the label get
elided in *all* languages, and also the issue it was working around is
no longer present; even with very long text, the combobox no longer gets
pushed out of view, and instead the formlayout first switches to mobile
view and then elides the Label, exactly as intended. So we can safely
remove the hack.

If a redirected animation reaches the end, the timeline value will be 0,
i.e. the interpolated() function has to return the from value, not `to`.
BUG: 438368
When the aboutToDestroy signal is emitted, the compositor object is
already partially destroyed. This contradicts to the name of the signal.
In addition to that, it will be better to call the stop method in the
destructors of X11Compositor and WaylandClient as it allows them to add
custom cleanup code when compositing is turned off.
If a window is animated using DeformEffect, allocate an offscreen
texture with the scale factor of the screen where the window is
considered to be on.
Also, resize the offscreen texture on demand in order to make resource
handling more efficient.
At the moment, we handle window quads inefficiently. Window quads from
all items are merged into a single list just to be broken up again.
This change removes window quads from libkwineffects. This allows us to
handle window quads efficiently. Furthermore, we could optimize methods
such as WindowVertex::left() and so on. KWin spends reasonable amount
of time in those methods when many windows have to be composited.
It's a necessary prerequisite for making wl_surface painting code role
agnostic.
Window quads need to be in some coordinate space. Since we want items to
be used not only for rendering windows, window-local coordinates do not
suffice.
This change makes scene items generate quads in the item-local coordinate
space.
The model matrix is used to map the quads to the global screen coordinate
system from the item coordinate space.
Since the quads are in the item local coordinate space, the mvp matrix
needs to be updated on every draw call. Given the render data, tracking
the last mvp matrix won't result in less glUniform calls. If this indeed
becomes a serious performance bottleneck, we can explore the possibility
of dumping mvp matrices in a UBO, which have been introduced in OpenGL
3.1.
The scene items depend on the scene windows for caching window quads.
The goal of this change is to move window quads management to item.
Merging window quads in one list and then splitting them is inefficient,
it will be highly desirable if window quads are removed from the public
api so we can optimize window quad management.
With this change, the window quad type becomes irrelevant to render
backends for the most part. Note that the Xrender backend is a bit
nitpicky about window quads, so the shadow item doesn't create generic
"WindowQuadShadow" quads anymore.
Drop-shadows with the software render backend impact performance quite
significantly. It also makes it easier to prepare render backends for the
item based design.
Use FontMetrics to calculate the expected max text width so it
doesn't overflow with wider fonts, specially in some languages
like pt_BR

Offers shoul be set on a source before data_device.set_selection. Doing
so afterwards appears to be against the spec and as such we may not pass
the update to wayland clients / klipper.
So far, we were creating a model view with the complete scene rendered
(even if we didn't render the windows themselves). This required us to
have a big glPerspective spanning the entire scene and we were just
cropping it as we rendered it into a smaller texture.
This changes our scenes so we have the correct matrix set up at all
times.
Specifically in the case of the Pinephone, this solves the following
issue where we were unable to connect external displays because it
exceeded GL_MAX_VIEWPORT_DIMS:

When the panel disappears, just reconsider the panel's state but don't
just stop sending updates to the input method.
Some input methods are just helpers that show and hide as necessary.
