The Xrender backend was added at the time when OpenGL drivers were not
particularly stable. Nowadays though, it's a totally different situation.
The OpenGL render backend has been the default one for many years. It's
quite stable, and it allows implementing many advanced features that
other render backends don't.
Many features are not tested with it during the development cycle; the
only time when it is noticed is when changes in other parts of kwin break
the build in the xrender backend. Effectively, the xrender backend is
unmaintained nowadays.
Given that the xrender backend is effectively unmaintained and our focus
being shifted towards wayland, this change drops the xrender backend in
favor of the opengl backend.
Besides being de-facto unmaintained, another issue is that QtQuick does
not support and most likely will never support the Xrender API. This
poses a problem as we want thumbnail items to be natively integrated in
the qtquick scene graph.
With the ongoing scene redesign, it needs to be rewritten. However,
given that it is not used widely based on support information from
various bug reports and our available man power is sparse, the most
reasonable thing is to drop the effect, unfortunately.

Many reasons have been brought up over the years for why this effect is
not appropriate to be enabled by default:
- It was designed to highlight the whizzy technical feature of being
able to make windows transparent, which is no longer particularly
impressive today.
- It looks visually dated.
- It can produce a confusing visual soup by blending a window being
moved or resized with the content below it, which we recently disabled
for the Highlight Windows effect.
- If one window is covering up another as a way to deliberately hide the
content of the lower window, this effect will reveal the hidden
content whenever the upper window is moved or resized at all.
Overall it does not seem to have enough advantages to offset these
issues. Let's disable it by default--but only for the people who did not
modify its configuration at all. We can assume that those people like
it, so let's keep it on for them.

With the new compositing scheduling, we want the screen to be redrawn as
close as possible to the next vblank. Furthermore, compositing is no
longer driven by a timer. This change removes the NoSwapEncourage swap
strategy as it doesn't make sense now, in addition to that it just does
not work on Wayland.
The following click behaviors are defined:
* Switch desktop and activate window [default]
* Switch desktop only
The former emulates the previous default of activating clicked windows
using the Present Windows effect. The latter introduces a new mode where
the clicked window is not activated, allowing the user to select a
virtual desktop without worrying about disrupting the last active
window.
The configuration toggle that controlled the use of the Present Windows
effect has been subsumed into the first click behavior, i.e., if the
effect is enabled, it will be implicitly triggered.
Summary:
If the listed interpreter does not exist, kconf_update skips the update.
The update script uses python3, so declare that properly.
Test Plan: Saw the error by accident, it's gone now.

Summary:
If a user has set his border size explicitly in the past also respect this
selection with the new auto border size mode by setting auto borders to
false on update.
For this a kconf_update file and a sed based shell script is added.
Test Plan: Manually.

Summary:
Now, when the scripting effects API has all required ingredients to port
the Scale effect to JavaScript we finally can do it.
The main rationale for porting this effect to JavaScript is that
scripted effects API lets us focus more on what we want instead of
"how".
Visually, the ported version doesn't deviate from the C++ version.
Test Plan:
* Enable the Scale effect;
* Open/close a window.

Summary:
There were several reasons to rewrite the Minimize Animation effect in
JavaScript: to simplify code and to get rid of full repaints. One could
say that nothing prevents us from calculating the dirty region in
postPaintScreen or postPaintWindow and it is correct, but with the
scripting effects API the dirty region will be calculated for us, so we
can focus more on "what we want" instead of "how".
Visually, the "old" effect and the rewritten one look quite the same.
Except one tiny bit: if a window doesn't have an icon in the task manager,
it won't be animated. The reason for that is the purpose of this effect is
to show where the window will be after it's minimized, if the window
doesn't have icon in the task manager, one can't click at the center of
the screen to unminimize the window.
There is one significant change, the name of the effect was changed to
"Squash". If we put this effect and the Magic lamp effect under "Window
Minimize Animation" category (or if we add some "heading" label), then
the old name and the name of the category would "conflict". The new name
was suggested by Nate Graham and it very closely describes what the
effect does. "Scale" doesn't fit this effect because while a window is
being animated, its aspect ratio is not preserved.
