This reverts commit 9d4c8fda09.
Unlike other effects this wasn't using hide/show as a hack for not
having a created/destroyed signal but because the window is internally
hidden when it's in auto-hide mode despite being still mapped.
BUG: 426686
This change replaces the remaining usages of the old connect syntax with
the new connect syntax.
Unfortunately, there are still places where we have to use SIGNAL() and
SLOT() macros, for example the stuff that deals with d-bus business.
Clazy was used to create this change. There were a few cases that needed
manual intervention, the majority of those cases were about resolving
ambiguity caused by overloaded signals.
Instead of looping through the rects in the region, emit the region at
bulk. It reduces the amount of emissions we do and allows us to pack the
response accordingly.
The region that we pass to the next paintWindow() cannot be larger than
the one that we've received. If an effect passes a larger region, the
tracked buffer damage will be messed up and user will see all sorts of
visual artifacts.
The results of the blur and the background contrast effect will never
be seen if the screen locker is active.
In order to avoid wasting computational resources, we could temporarily
disable the blur effect until the screen is unlocked.
Furthermore, given that the blur effect shrinks the clip region, it is
guaranteed that the compositor will have to render the desktop window
behind the lockscreen window. With this change, all windows behind the
screen locker will be properly clipped away.
The original purpose of m_damageArea was to indicate which region of the
blur cache became dirty and needs to be updated. However, we no longer
need to keep track of damaged area since the blur cache was removed.
The main advantage of SPDX license identifiers over the traditional
license headers is that it's more difficult to overlook inappropriate
licenses for kwin, for example GPL 3. We also don't have to copy a
lot of boilerplate text.
In order to create this change, I ran licensedigger -r -c from the
toplevel source directory.
Summary:
Restrict to process with `X-KDE-DBUS-Restricted-Interfaces=org.kde.kwin.Screenshot` in their corresponding Service file,
to take screenshots.
Such a program can now take immediate screenshots.
Adds a utility file to group KService related logic.

windowShown and windowHidden are emitted when the window becomes visible
and hidden, respectively. For example, that can be the case when the
window has been minimized or unminimized. We have to start animations
only when windowAdded or windowClosed has been emitted.

The text caret tracking feature allows to keep the text caret inside the
zoomed area. It can be especially useful when the zoomed area is smaller
than the text editor.
BUG: 362189
Currently, the focus tracking functionality in the zoom effect does not
work because it relies on kaccessibleapp, which is dead. Luckily for us,
there is a library called libqaccessibilityclient that provides a way
to monitor focus changes.
BUG: 421234
Summary:
Present windows works as follows:
- It moves all windows about until nothing is overlapping with any
other window.
- This doesn't resize anything so ultimately we end up with a new
co-ordinate space that's bigger than the screen depending on the amount
of overlap.
- We then render this whole view transformed to the screen
The rectangle "bounds" is in overviewpixels, with "scale" being the
ratio to convert to screen pixels.
When adjusting the new bounds there's an attempt to centre align things.
As bounds is in "overviewpixels" we multiply references to the previous
bounds by scale, and divide everything through at the end. bounds.x/y
were missed.
This is mostly unoticable except on massive super-ultra-wide monitors
which will otherwise have a tendency to shift to the left.
Test Plan:
Kai created a whole new test framework for this code that copy pasted
this algorithm then showed mock windows as rectangles

Summary:
cca0e15b45 broke code that calculates the value of the fps counter.
The frames field stores timestamps of previous frames, not time between
each two consecutive frames.
This change doesn't attempt to make the show fps compute more accurate
performance metrics, e.g. how much times it takes to execute rendering
commands on the GPU, etc.
Test Plan: The Show FPS effect displays more sensible values.

Summary:
Add a shouldReturnNativeSize to screenshotFullscreen so that KWin can export
screenshot that are screen pixel accurate.
Useful for spectacle to be able to do rectangular selection kind of screenshot.
Test Plan:
Example of a top screen using a 1.25 scale ratio being export in native resolution
{F8255144}
(The top screen has a bigger size than its virtual geometry and next screen doesn't overlap)
Example of the same screen in virtual resolution:
{F8255146}

Summary:
The screenshot made on screens with scale factor were downscaled by their scale factor making them blurry.
It prevents taking screenshots of missing Hidpi related bugs showing the issues under Wayland.
This fix the case of a single screenshot, but not the rest:
Multiscreen screenshot downscales the screen using scale factor.
Spectacle rectangular selection screenshot is broken as soon as some scale factor different than 1 is used on any screen.
Test Plan:
Under Wayland with a scale factor on a screen, take a screenshot using spectacle.
The output image is not downscaled and has the same size as the screen resolution.
No other change to any other screenshot mode, or under X.

Summary:
We build some objects several times which makes it uncomfortable to develop KWin
since every time we modify something a lot of things get rebuilt. This should
help a bit although it doesn't solve all the problems.

Summary:
The "Candy" category suffers from some problems:
- It does not need to exist; everything in it is purely appearance-related and could live in the existing "Appearance" category
- The name is inappropriate; "Eye Candy" would be better, but changing it to this has proven controversial in the past
Let's just remove the category and move everything in it into the "Appearance" category.
Test Plan:
Apply and compile
Open Desktop Effects KCM
See that the "Candy" category is no more and the "Appearance" category has more stuff in it
